which graph represents a reflection of f(x) = 6(0.5)x across the x-axis?

on a coorindate plane, an exponential function starts in quadrant 3 and increases and approaches y = 0 in quadrant 4. it crosses the y-axis at (0, 6) and goes through (1, negative 3).
on a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. it goes through (1, 3) and crosses the y-axis at (0, 6).
on a coordinate plane, an exponential function approaches y = 0 in quadrant 3 and decreases into quadrant 4. it goes through (negative 1, negative 3) and crosses the y-axis at (0, negative 6).
on a coordinate plane, an exponential function decreases from quadrant 2 to quadrant 1 and approaches y = 0 in the first qudrant. it goes through the y-axis at (0, 6) and goes through (1, 3).
