Answer
For any given $z$ value, the graph of $q(z-2 b)+a b$ is $2 b$ units to the right and $a b$ units above the graph of $q(z)$
Work Step by Step
From the inside change, we know that the graph is shifted $2 b$ units to the right. From the outside change, we know that it is shifted $a b$ units up. So, for any given $z$ value, the graph of $q(z-2 b)+a b$ is $2 b$ units to the right and $a b$ units above the graph of $q(z)$.
