Best ResponseYou've already chosen the best response.0Belinda wants to invest $1000. The table below shows the value of her investment under two different options for three different years: Number of years 1 2 3 Option 1 (amount in dollars) 1300 1690 2197 Option 2 (amount in dollars) 1300 1600 1900 Part A: What type of function, linear or exponential, can be used to describe the value of the investment after a fixed number of years using option 1 and option 2? Explain your answer. (2 points) Part B: Write one function for each option to describe the value of the investment f(n), in dollars, after n years. (4 points) Part C: Belinda wants to invest in an option that would help to increase her investment value by the greatest amount in 20 years. Will there be any significant difference in the value of Belinda's investment after 20 years if she uses option 2 over option 1? Explain your answer, and show the investment value after 20 years for each option. (4 points)

Best ResponseYou've already chosen the best response.0Part A is asking about linear and exponential function, you know the different between em right?

Best ResponseYou've already chosen the best response.0so a guyyy??? Like I am really slow btw

anonymous

Best ResponseYou've already chosen the best response.0you can prolly guess which one is a linear function and exponential just by looking

anonymous

Best ResponseYou've already chosen the best response.0i can but i dont know about you

anonymous

Best ResponseYou've already chosen the best response.0option one is exponential and option 2 is linear

Best ResponseYou've already chosen the best response.0but for the explanation part

anonymous

Best ResponseYou've already chosen the best response.0option two is linear because it increases by a fixed amount?

Best ResponseYou've already chosen the best response.0okay so "option two is linear because it increases by a fixed amount"

Best ResponseYou've already chosen the best response.0when you did the last question, exponential increase by what factor?

anonymous

Best ResponseYou've already chosen the best response.0the f(x) of your last question

anonymous

Best ResponseYou've already chosen the best response.0its a compounding 3%

anonymous

Best ResponseYou've already chosen the best response.0yes...but this question doesn't have an equation.

anonymous

Best ResponseYou've already chosen the best response.0yea that f(x) is an exponential equation just like option 1

Best ResponseYou've already chosen the best response.0they have different flavors but they increase to a very steep gradient in the end

anonymous

Best ResponseYou've already chosen the best response.0increase or decrease depends on the function

anonymous

Best ResponseYou've already chosen the best response.0they dont behave like a linear function which looks like this on the graphdw:1438877675414:dw

Best ResponseYou've already chosen the best response.0option 2 first: its y=mx+b option 1: you want me to hand you compound interest formula?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0what? I know y=mx+b. But how does that apply to this? and yes please

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0y=mx+b b is your yintercept where its year 0 which is 1000. now from there what is the rate of change of the $$$ per year? that will be your m

anonymous

Best ResponseYou've already chosen the best response.0compound interest formula\[A=P(1+\frac{ r }{ 100 })^n\]

anonymous

Best ResponseYou've already chosen the best response.0A=amount accumulated P=principal amount r=interest rate n=years

anonymous

Best ResponseYou've already chosen the best response.0yes I know that we were taught this: f(x)=p(1+r)^x where r was the rate in decimal form, p was principle and x was x

anonymous

Best ResponseYou've already chosen the best response.0y=mx+1000 1000 is your principal

Best ResponseYou've already chosen the best response.0now lets find your m with 2 points

anonymous

Best ResponseYou've already chosen the best response.0ok, what about 1 and 0

anonymous

Best ResponseYou've already chosen the best response.00 is year 0, whats your $ at year 0?

anonymous

Best ResponseYou've already chosen the best response.0for option B?its 1000

anonymous

Best ResponseYou've already chosen the best response.0now year 1 of option b?

anonymous

Best ResponseYou've already chosen the best response.0now you have your 2 points (0,1000) and (1,1300)

anonymous

Best ResponseYou've already chosen the best response.0you can find your slope from here

anonymous

Best ResponseYou've already chosen the best response.0\[m=\frac{ y_2y_1 }{ x_2x_1 }\]

Best ResponseYou've already chosen the best response.0nvm ill show you the simple interest formula so you dont get confused

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0\[I=P \times R \times T\]

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0interest rate is \[\frac{ 13001000 }{ 1000 } \times 100\] I = interest created P = principal R = interest rate T = time

Best ResponseYou've already chosen the best response.0we are still on part B?

anonymous

Best ResponseYou've already chosen the best response.0okay. What was that the answer to? 30

anonymous

Best ResponseYou've already chosen the best response.0now we are support to create function

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0we piece the part of the simple interest formula + principal to get the answer

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0like this f(x)=x+(P*R*T)

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0oops its f(x)=1000+(1000*R*x)

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0since x is time which is the only thing that changes

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0test this function see if it works

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0So the answer to part B for Option 2<< or 1 am not sure is f(x)=1000+(1000*R*x)

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0lets see...\[f(1)=1000+(1000*0.3*1)=1300\]\[f(2)=1000+(1000*0.3*2)=1600\]

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0thats good for your part b option 2

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0for option 1 its the compound interest formula, you can find your interest rate like this\[\frac{ 13001000 }{ 1000 } \times 100\]

Best ResponseYou've already chosen the best response.0\[f(x)=1000(1.3)^x\]

anonymous

Best ResponseYou've already chosen the best response.0"f(1)=1000+(1000∗0.3∗1)=1300 f(2)=1000+(1000∗0.3∗2)=1600" for option b?

anonymous

Best ResponseYou've already chosen the best response.0nah its \[f(x)=1000+(1000*0.3*x)\]you can simplify it further if you like to

anonymous

Best ResponseYou've already chosen the best response.0not literal essay, I mean its not graded by the computer, its by the teacher, so I am not sure what specifically the answer is, since ther are no multiple choice.

anonymous

Best ResponseYou've already chosen the best response.0they are asking you to craft a function that whenever you put in a year, it will churn out something that tells you the $ you get when you put your $ in for that amount of year

Best ResponseYou've already chosen the best response.0where is the n in the function for option 1? f(x)=1000(1.3)x WOAH WOAH WOAH JUST TO GET THIS ALL CLEAR, OPTION 2: f(x)=1000+(1000*0.3*n) OPTION 1:f(x)=1000(1.3)x

anonymous
