Compute the following average rates of change for the function f(x) = Vx. Show your work and round your answers to 5 decimal places. Then use these rates to estimate the instantaneous rate of change at x = 4. Estimate does NOT mean guess. Estimate means to make a logical approximation based on your calculations. A. Find the average rate of change from x = 4 to x = 9. B. Find the average rate of change from x = 4 to x = 5. C. Find the average rate of change from x = 4 to x = 4.1. D. Find the average rate of change from x = 4 to x = 4.01. E. The instantaneous rate of change at x = 4 is
