Expert Solution
Step 1

Find the rate of change of a function using a graph essentially means that we need to find the slope of the curve represented by the graph in the neighborhood of the point of interest.

So given a point (b,f(b)) on the graph of the function f(x), to find its rate of change at this point, we need to find the following ( considering a neighboring point (b,f(b)) )

rate of change=f(b)-f(a)b-a

This essentially represents the slope of the tangent to the function curve at the point (b,f(b))
