2. Let f be the function whose graph is given below: Use the function above to answer all of the following: a) Find the average rate of change on the interval [-1,1]. b) Find the average rate of change on the interval [0,1]. (60) c) Estimate the value of f'(2) O d) Estimate the value of f(1). e) Estimate the value of f'(-1.5). f) Estimate the value of f'(3) g) Estimate the value of f'(-3) = h) Estimate the value of f'(4.25) i) Using those estimations sketch a possible graph of f'(x), i) Write the equation of the tangent line to the graph f(x) at x = 0.
