Here's the question you clicked on:

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
try doing the function of time by distances traveled so in a graph: |dw:1366300640356:dw|
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.
well thanks for the help anyway! :)

Is that it or is that only a small step for the "big picture"
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?
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
I am sorry I was busy, now I am back
typo on my previous post it's D = f(t) = 60t
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
you can now apply it to the example we want to use
it's written just like how I've written them. you might want to rephrase. Did you read the link I sent you?
You wrote so much I am not sure what I am supposed to use
so what don't you understand?
