Function B increases at a faster rate. The rate of change for A is 1. The rate of change for B is 1.5.
In order to find the rate of change for each so that we can compare, we need to use the following formula.
Change = (y2 - y1)/(x2 - x1)
In which (x1, y1) is the original point (x = 2) and (x2, y2) is the second point (x = 3). So, let's use the equation for each set of points.
FUNCTION A
Change = (y2 - y1)/(x2 - x1)
Change = (0 - -1)/(3 - 2)
Change = 1/1
Change = 1
FUNCTION B
Change = (y2 - y1)/(x2 - x1)
Change = (0 - -1.5)/(3-2)
Change = 1.5/1
Change = 1.5
