Answer:
d. 289
Explanation:
You want to solve the function of q when function of r has an input of 5.
Might sound confusing but find the output of function r(x) with the input of
x = 5.
From the r(x) chart:
r(5) = -17
Now substitute that in the original question:
q(r(5)) = q(-17)
Look at the q(x) chart next, as you can see:
q(-17) = 289
So all in all:
q(r(5)) = 289
Cheers!
