Optimization Problems: To approach these problems, we need to find extrema using the first derivative. But first, find the equation that relates the two unknowns so that f(x)=y. Then, substitute in y for an x value (find their relationship) and differentiate the function in terms of x. Find the x value of the extrema to answer the problem.
