Which graph represents an exponential decay function?
On a coordinate plane, a curve opens up and to the right in quadrant 4.
On a coordinate plane, a curve opens up and to the right in quadrants 1 and 2. The line rapidly decreases in quadrant 2 and then curves and approaches the x-axis in quadrant 1.
On a coordinate plane, a line slightly curves up in quadrant 1.
On a coordinate plane, a line slowly increases in quadrant 2 and then increases rapidly into quadrant 1.
