See a solution process below:

To fing $h(-1)$ substitute $color(red)(-1)$ for each occurrence of $color(red)(-1)$ and the calculate the result:

$h(color(red)(x)) = -color(red)(x)^2 - 3$ becomes:

$h(color(red)(-1)) = -color(red)((-1))^2 - 3$

$h(color(red)(-1)) = -1 - 3$

$h(color(red)(-1)) = -4$
