Determine the average rate at which the quadratic function y = .02 t² + -2.4 t + 77 changes between clock times t = 32.2 and t = 32.2 + .1 sec; between clock times t = 32.2 and t = 32.2 + .01 sec; and between clock times t = 32.2 and t = 32.2 + .001 sec. At what rate do you conjecture this function will be changing at the instant t = 32.2 sec?
