The graph of a function is shown on the coordinate plane below. Identify the rate of change of the function.

3.25

Step-by-step explanation:

according to the systematical theorem it would equal 3.25

what's that

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
