Answer:

f(-2) = 13

g(4) = -9

Explanation:

Whenever a question is asking you to find something like, in this example, f(-2) or g(4), you have to substitute whatever number is in the parentheses for every x in the function with that letter.

Let's try to find f(-2). We have to substitute -2 for every x in the function f and simplify:

$f(-2) = -2 (-2)^{3} -3\\f(-2) = -2(-8)-3\\f(-2) = 16 - 3 \\f(-2) = 13$

Therefore, $f(-2) = 13$ .

Next, let's try to find g(4). We have to substitute 4 for every x in the function g and simplify:

$g (4) = -2(4) - 1\\g(4) = -8-1\\g(4) = -9$

Therefore, $g (4) = -9.$
