Step-by-step explanation:

5

Answer 2

Answer:

$\boxed {21}$

Step-by-step explanation:

Find $g(5)$:

$g(x) = x^{2} - 4$

-Apply $5$ for variable $x$ to the equation:

$g(5) = (5)^{2} - 4$

-Solve the expression:

$g(5) = (5)^{2} - 4$

$= 25 - 4$

$= \boxed {21}$

Therefore, the final answer is $21$.
