Question

What is the transformation that occurs to the equation y = 2^x if it changes to y=-2^x-2

The graph is reflected across the y-axis and moves 2 units up.

The graph is reflected across the x-axis and moves 2 units up.

The graph is reflected across the x-axis and moves 2 units down.

The graph is reflected across the y-axis and moves 2 units down.

Answer 1

The negative out front flips the graph upside down, and the -2 at the end indicates that it moves along the y axis either up or down.

Answer 2

In your case it flips it across the x axis and moves it down two units. Choice 3 is the one you want.
