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

 

graph:    http://www.desmos.com/calculator/qsmzdsxcsu

 

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.
