The value of the function g(x) = x² - 4 at g(5) is 21. Option C is correct.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The expression is solved as:-

g(x) = x² - 4

To calculate the value g(5) put x=5 in the expression.

g(5) = ( 5 )² - 4

g(5) = 25 - 4

g(5) = 21

Therefore, the value of the function g(x) = x² - 4 at g(5) is 21. Option C is correct.
