Suppose that the functions q and r are defined as follows.
q (x) = -3x-2
r（x） =8+4
Find the following.
1. q(r(-4)
2. r(q(-4)
1. q(r(-4)) = q(8+4) = q(12) = -3(12) - 2 = -36 - 2 = -38
2. r(q(-4)) = r(-3(-4) - 2) = r(14) = 8 + 14 = 22
q (x) = -3x-2
r（x） =8+4
Find the following.
1. q(r(-4)
2. r(q(-4)
2. r(q(-4)) = r(-3(-4) - 2) = r(14) = 8 + 14 = 22
