Suppose that the functions q and r are defined as follows.
q (x) = -3x-2
r（x） =8+4
Find the following.
q(r(-4)
First, we need to find r(-4) by plugging -4 into the function r(x).
r(-4) = 8 + 4 = 12
Now, we need to find q(r(-4)) by plugging 12 into the function q(x).
q(12) = -3(12) - 2
q(12) = -36 - 2
q(12) = -38
Therefore, q(r(-4)) = -38.
