Question

given the function $f(x) = x^2 + 7$, find the indicated values.
\ta) $f(7)$\t\t\t\t\tb) $f(a)$

\ta) $f(7) = 56$ (simplify your answer.)
\tb) $f(a) = \square$ (simplify your answer.)

Explanation:

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

Given \( f(x)=x^{2}+7 \), replace \( x \) with \( a \).
\( f(a)=a^{2}+7 \)

Answer:

\( a^{2} + 7 \)
