Question

Evaluate the function.
f(x) = 3x2 + 16
Find f(-1)

Answer 1

`f(-1)=19`

Explanation:

Evaluating Functions

Given a function y=f(x), evaluate the function for x=a means substituting the variable for the given value.

We have the function:

`f(x)=3x^2+16`

Find f(-1):

`f(-1)=3(-1)^2+16`

`f(-1)=3(1)+16`

`f(-1)=3+16`

`\boxed{f(-1)=19}`
