Find the average rate of change of f (x) = 4x\"Z 7 on the interval [1, b]. Use the graph shown to estimate the local extIema of the function, determine the intervals on which the function is increasing and decreasing and to determine the intervals on which the fun tion is concave up and concave down. Is the function described in the table below increasing or decreasing? Concave up or concave down?
