PLS HELP! URGENT!! Calculate the average rate of change of f over [−4, 5]. Is the instantaneous rate of change of f ever equivalent to the average rate of change of f over [−4, 5]? If so, how many times are they equal in the given interval? (4 points)

Part B: Estimate the equation of a tangent line at x = −1 for the graph of f. (2 points)

Part C: Find the value for each of the limit as x approaches negative 2 of the quantity f of x minus f of negative 2 all over the quantity x minus negative 2 and the limit as x approaches 2 of the quantity f of x minus f of 2 all over the quantity x minus 2 or explain why it does not exist.
