Which function represents a reflection of f (x) = 5 (0.8) x across the x-axis?

g (x) = 5 (0.8) - x

g (x) = - 5 (0.8) x

g (x) = (0.8) x

g (x) = 5 (-0.8) x

The function f (x) = 5 (0.8) x is located in the first quadrant, forming a increasing curve. Imagine the reflection of the graph of the function. It is located in the fourth quadrant, forming a decreasing curve.

The graph that shows reflection is just the negative of the function. So the answer is (x) = - 5 (0.8) x
