Question

Hi I need help with this question please!!! I don’t understand it :/

Answer 1

The above answer is correct. Great job

Answer 2

- 22.5

Explanation:

Substitute x = 3 into f(x) and x = 16 into h(x) , then

`(1)/(2)` g(3) - h(16)

=
`(1)/(2)` × - 3(3)² - (2
`√(16)` + 1)

=
`(1)/(2)` × - 3(9) - (2(4) + 1)

=
`(1)/(2)` × - 27 - (8 + 1)

= - 13.5 - 9

= - 22.5
