Question

If f(x) = -2x^2 + 3 then f (-3) =
1) -15
2) 21
3) 39
4) -18

Answer 1

1) -15

Explanation:

Hi there!

In order to solve this problem, plug in -3 for all the x-values.

Your equation will become
`-2(-3)^2 +3.`

Now all you have to do is solve!

`-2(9) + 3`

`-18 + 3`

`-15`

f(-3) = -15

I hope this helped!
