Question

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

Answer 1

Answer:

$f(-1)=19$

Step-by-step 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):

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

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

$f(-1)=3+16$

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