Answer:
See blue graph in attached picture.
Explanation:
A reflection across the x-axis occurs when a negative is place at the front of the function. So f(x) = 6(0.5)^x becomes -6(0.5)^x. The original is graphed below in green. The reflection is in blue. The graph will be flipped across the x-axis perpendicular and equal distance from the axis.
