Give the equation of the exponential function whose graph is shown. -4 4 -2 4 10 x y left parenthesis 1 comma one third right parenthesis y equals 0 (-1,3) (0,1) A coordinate system has a horizontal x-axis labeled from negative 4 to 4 in increments of 1 and a vertical y-axis labeled from negative 2 to 10 in increments of 1. From left to right, a curve falls steeply in quadrant 2 passing through (negative 1, 3), crosses the y-axis at (0, 1), and then falls shallowly in quadrant 1 passing through (1, one third). As x increases towards positive infinity, the curve approaches the positive x-axis from above. All points are plotted and labeled.
