Example 3 - Rate of Change and Graphs
Find the average rate of change of 𝑔𝑥 over the interval −2,1 
Which labelled point has the greatest rate of change? Which labelled point has the least rate of change?
Give an example of an interval over which the average rate of change of 𝑔𝑥 is zero.
Which of these is a reasonable guess for the rate of change at the point labelled 𝐴?
−4             B. 0          C. 32            D. 8
