Answer:
Given f(x) = 5x, find each of the following:
f(3) = 15
f(-2) = -10
fo
f(-1) = -5
f(8) = 40
f(-4) = -16
Step-by-step explanation:
When you have a value of x, it shows up inside the parenthesis.
For example: f(3) means x = 3.
Once you know what x is, you just have to plug in it's value into the original function.
So f(x) = 5x where f(3) means (5*3) or 15.
