Consider the following problem. A bicyclist is riding on a path modeled by the function f(x) = 0.08x, where x and f(x) are measured in miles (see figure). Find the rate of change of elevation at x = 3. y 3 2 f(x)=0.08 x LI 1 1 2 3 4 5 6 -1 Decide whether the problem can be solved using precalculus, or whether calculus is required. O The problem can be solved using precalculus. O 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. X
