Are there any requirements or guidelines that the function has to have?

If there aren't any, here's a simple one....

function:      y = (4/5)x         , x ≥ 0

real life situation:     It costs \$4.00 to buy 5 apples. What is the price for any number of apples ?

x (input)    =   number of apples

y (output)  =   total price

table:

___x,__ number of apples___ ___y,__ price in dollars___
1 0.80
2 1.60
3 2.40
4 3.20
5 4.00

domain: all real numbers ≥ 0

range:  all real numbers ≥ 0

Does your function have a positive or negative slope? Why?

It has a positive slope because the more apples you buy, the higher the price.

What is the relationship between your input and output?

y is directly proportional to x.
