Which graph shows exponential growth? on a coordinate plane, a parabola opens up with vertex at (0, 0). on a coordinate plane, a curve approaches y = 0 in quadrant 2 and curves up into quadrant 1. on a coordinate plane, a straight line with positive slope crosses the y-axis at (negative 1, 0) and crosses the y-axis at (2, 0). on a coordinate plane a curve opens down and to the right in quadrants 1 and 4. it crosses the x-axis at (1, 0).
