Consider the following problem. A bicyclist is riding on a path modeled by the function f(x) = 0.04(8x − x2), where x and f(x) are measured in miles. Find the rate of change of elevation when x = 2. (Round your answer to two decimal places. ) Decide whether the problem can be solved using precalculus, or whether calculus is required. The problem can be solved using precalculus. The problem requires calculus to be solved. If the problem can be solved using precalculus, solve it. If the problem seems to require calculus, use a graphical or numerical approach to estimate the solution.
