Let P(h) = 23 exp(−1.1h) where we are using "exp" to denote the exponential function with base e. That is exp(u) = eª Approximate the instantaneous rate of change in P(h) at h = 1.7 by computing the average rate of change from 1.7 to 2.8. Enter your answer as a decimal. Round to three decimal places (as needed).
