Can anyone show me how i would figure this problem out

The value of x is the number inside the parenthesis, so h(-4) gives x a value of -4.

The equation says when X is ≤ -4 use the first equation

So h(-4) = -1/2(x) -15

= -1/2(-4) -15

= 2 -15

= -13

When x = -2 (h(-2) ) use the 2nd equation:

h(-2) = 20-3x^2

=20-3(-2)^2

= 20-3(4)

=20-12

=8

Now you have -13 + 3(8)

= -13 + 24

=11

The answer should be 11

it is x equals 3   plese mark me really need it
