Question

A function is defined by f (x) = StartFraction x Over 4 EndFraction. What is f(–8)?

Answer 1

-2

Explanation:

To evaluate a function, replace the variable by the function argument and simplify.

Application

`f(x)=(x)/(4)\\\\f(-8)=(-8)/(4)\qquad\text{replace x with -8}\\\\\boxed{f(-8)=-2}\qquad\text{simplify}`
