The functions q and r are defined as follows.
Q (x) = 5х- 1
r (x) = -3x+5
Find the value of q (r (-2)).
First, we need to find the value of r(-2) by plugging -2 into the function r(x):
r(-2) = -3(-2) + 5 = 6 + 5 = 11
Now that we have found r(-2) to be 11, we can plug this value into the function q(x):
q(11) = 5(11) - 1 = 55 - 1 = 54
Therefore, the value of q(r(-2)) is 54.
