give an example of a function. Give the relation as a set of ordered pairs. Use a test such as mapping or the verical line test to show if your set of ordered pairs is a function. An example of a function could be: distance traveled and time, or the cost of a turkey and its weight. You can list your relation as a set of ordered pairs, or as a table. In either case, you must prove the relation is a function

functions are written in this format f(x)= some equation this is similar to y = mx + b the f(x) is the y read a little bit about functions http://finedrafts.com/files/math/precal/Larson%20PreCal%208th/Larson%20Precal%20CH2.pdf

so for example: a car is traveling 60 kilometers per hour (we need to label our graph accordingly). we need to be able to show how long will it take for a car to travel 35 miles, 45 miles and maybe 50 miles.

Is that it or is that only a small step for the "big picture"
nincompoop
  • nincompoop
big picture. you need to be able to represent your equation graphically and mathematically

can you come up with a formula that determines the function of time?
nincompoop
  • nincompoop
we said that the the rate of speed is 60 km/hr so in minutes: that is 60 km/60 mins since 1 hour is 60 mins 60/60 is 1. So now, we have 1 km/min D=f(t)=1t if we want to use the rate rate per minute D=f(f)=60t if we want to use the rate per hour

typo on my previous post it's D = f(t) = 60t
LazyBoy
  • LazyBoy
oh okay
nincompoop
  • nincompoop
so pretty much there's your equation and you can do your algebra to determine time or distance

okay, but I am not sure how I am supposed to submit my assignment. I mean like what information should I include and how should i write it
nincompoop
  • nincompoop
you can now apply it to the example we want to use
nincompoop
  • nincompoop
it's written just like how I've written them. you might want to rephrase. Did you read the link I sent you?
LazyBoy
  • LazyBoy
yes, I did
LazyBoy
  • LazyBoy
You wrote so much I am not sure what I am supposed to use
nincompoop
  • nincompoop
so what don't you understand?
