Determine the cubic function obtained from the parent function y = g after each sequence of transformations

a reflection across the x-axis; a translation 1 unit up; and a translation 2 units right

The parent function is y = g(x).

First, we have a reflection across the x-axis. This transforms the graph to y = -g(x).

Next, we have a translation 1 unit up. This transforms the graph to y = -g(x) + 1.

Finally, we have a translation 2 units right. This transforms the graph to y = -g(x-2) + 1.

Therefore, the resulting cubic function is y = -g(x-2) + 1.
