Answer 1

D

Explanation:

I figured out the hard way

Answer 2

`g(x) = -x^2 + 3`

Explanation:

Given

`f(x) = x^2`

Required

Determine g(x)

First, shift f(x) down by 3 units

The rule is:

`f'(x) = f(x) - 3`

So:

`f'(x) = x^2 - 3`

Next, reflect f'(x) across the x-axis to get g(x)

The rule is:

`g(x) = -f(x)`

So, we have:

`g(x) = -(x^2 - 3)`

Open bracket

`g(x) = -x^2 + 3`
