1 The graph of a function is given Determine the average rat

1. The graph of a function is given. Determine the average rate of change of the function between the indicated points on the graph. (Assume that the points lie on the grid lines.)

_______

2. The graph of a function is given. Determine the average rate of change of the function between the indicated points on the graph. (Assume that the points lie on the grid lines.)

_______

Solution

1) Two points indicated on graph: ( 5, 1) and ( 1, 3)

Avg rate of change = ( 3-1)/( 1 -5) = -2/4 = -1/2

2)

Two points indicated on graph: ( 5, 2) and ( -1, 0)

Avg rate of change = ( 2 - 0))/(5 - (-1)) = 2/6 = 1/3
