Answer:
[tex]f(-1)=19[/tex]
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:
[tex]f(x)=3x^2+16[/tex]
Find f(-1):
[tex]f(-1)=3(-1)^2+16[/tex]
[tex]f(-1)=3(1)+16[/tex]
[tex]f(-1)=3+16[/tex]
[tex]\boxed{f(-1)=19}[/tex]
