Explain in words the effects of the transformations given in by the formula $$q(z + b) - a.$$ on the graph of $q(z)$. Assume $a$ and $b$ are positive constants. For each shift, enter the parameter or number which identifies the amount of the shift, and then select the direction of the shift in the pulldown menus.

The graph of $\ q(z + b) - a \ $ is units ? to the left of to the right of the graph of $q(z)$, and units ? above below the graph of $q(z)$.
