Let f(x) = 4Vx + 1. a. What is the average rate of change of f over the interval from a = 2 to a = 3.5? Preview b. What is the average rate of change of f over the interval from x = 3.5 to a = 5.7? Preview c. f(a) = 62.19 and the average rate of change of f over the interval from x = a to z = a + 170 is 0.113. What is the value of f(a + 170) ? (Hint: think of the average rate of change as a constant rate of change.) f(a + 170) = Preview
