The graphs of f and f are shown over the domain [-8, 1]. Graph of f Graph of f' Part A: Calculate the average rate of change of f over [-8, 1]. Is the instantaneous rate of change of fever equivalent to the average rate of change of f over [-8, 1]? 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 = -3.5 for the graph of f. (2 points) lim f(x)-f(-1) lim f( x) -f(-5) Part C: Find the value for each of x- -1 x-(-1) and x- -5 x-(-5) or explain why it does not exist. (4 points)
