Does your function have a positive or negative slope? Why?
What is the relationship between your input and output?
+9481 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.
