Question

given the function $f(x) = x^2 + 11$, find the indicated values.

a) $f(11)$

b) $f(a)$

a) $f(11) = 132$ (simplify your answer.)

b) $f(a) = \square$ (simplify your answer.)

Explanation:

Step1: Substitute \( x = a \) into \( f(x) \)

To find \( f(a) \), we replace \( x \) with \( a \) in the function \( f(x)=x^{2}+11 \). So we get \( f(a)=a^{2}+11 \).

Answer:

\( a^{2} + 11 \)
