Question

If g(x) = x2 − 4, find g(5).

Answer 1

21

Explanation:

5

Answer 2

`\boxed {21}`

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`.
