3. For the given function below [3] a. Calculate the average rate of change between x = -1 and x = 0 b. The tangent line at x = -1 has been graphed and its equation can be approximated by y = - 6.6 x + 6. Use the tangent to calculate the instantaneous rate of change at x = -1 _ Consider the function f(x) = 2(3) -x 20 18 16 14
