Answer:
The graph in the lower left corner.
Step-by-step explanation:
The graph of [tex]y=2^x[/tex] is in the upper right-hand corner.
The graph of [tex]y=-2^x[/tex] (reflected about the x-axis) is in the upper left-hand corner.
The graph of [tex]y=-\frac{1}{2}(2^x)[/tex] is a vertical compression of [tex]y=-2^x[/tex], the points are half as far away from the x-axis -- squeezed closer to the x-axis by half.
