On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases from quadrant 2 into quadrant 1. it crosses the y-axis at (0, 1). which function is a shrink of the exponential growth function shown on the graph? f(x) = 2(3)x f(x) = one-half(3)x f(x) = 2(one-third) superscript x f(x) = one-half (one-third) superscript x
