Answer 1

-21

Explanation:

I recommend telling the person who wrote this to either install Grammarly, or check out that red squiggly line thingie.

By f(-3), that refers to f(x), so x = -3.

We can plug in the -3 into the formula.

-4(-3)^2 + 15

Solve:

-3 x -3 = 9.

= -4(9) + 15

= -36 + 15

= -21
