Question

Find f (5), f(x) =x^2-13t-30

Answer 1

-13t - 5

Explanation:

Put x as 5 and solve for the function.

f(5) = (5)² - 13t - 30

Splve for the exponent.

f(5) = 25 - 13t - 30

Add or subtract like terms.

f(5) = -13t - 5

Answer 2

`f(5) = -13t-5`

Explanation:

=>
`f(x) = x^2-13t-30`

Put x = 5

=>
`f(5) = (5)^2-13t-30`

=>
`f(5) = 25-30-13t`

=>
`f(5) = -13t-5`
