Determine which graph represents a reflection across the x-axis of f(x) = 3(1.5)x.

On a coordinate plane, an exponential function approaches y = 0 in quadrant 3 and then decreases in quadrant 4. It crosses the y-axis at (0, negative 0.5).

On a coordinate plane, an exponential function approaches y = 0 in quadrant 3 and then decreases in quadrant 4. It crosses the y-axis at (0, negative 3) and goes through (2, negative 7).

On a coordinate plane, an exponential function approaches y = 0 in quadrant 3 and then decreases in quadrant 4. It crosses the y-axis at (0, negative 3) and goes through (0.5, negative 7).

On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and then increases in quadrant 1. It crosses the y-axis at (0, 3).
