I WILL MEDAL/FAN NO DIRECT ANSWERS :) Belinda 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) 1100 1210 1331 Option 2 (amount in dollars) 1100 1200 1300 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)

linear functions increases by same magnitude each step because they run on straight slopes, exponential functions have curves and they dont run by the normal straight slope
anonymous
  • anonymous
so you should know whats the answer for part A
anonymous
  • anonymous
basically its asking you about simple interest and compound interest
anonymous
  • anonymous
so Part A: Option 1 is linear because it makes a straight line when it is graphed. Option 2, is exponential, because unlike option 1, it does not make a straight line.

ill hand you the compound interest formula \[A=P(1+\frac{ r }{ 100 })^n\]A=amount accumulated, P=principal amount, r=interest rate, n = number of years

  • anonymous
yea
anonymous
  • anonymous
the simple interest one you can just make a line equation to figure it out
anonymous

option 1 is not linear. option 2 is linear
anonymous
  • anonymous
option 2 increases by 100 each year
anonymous
  • anonymous
option 2 goes like 1000->1000+100->1000+100+100
anonymous
  • anonymous
option 1 is 1000->1000*1.1->1000*1.1^2 ->1000*1.1^3
anonymous
  • anonymous
once you have squares and cubes its not linear anymore
anonymous

i need to sleep now so good luck, you should be able to figure it out with all these information
