Use the chain rule (section 14.6) to find a formula df/dx if f = f(x, y) and y = g(x). Use your answer to question 1 to find dA/dx if A = xy and y = 6 - 2x2. Leave your answer in terms of x and y. Use your answer to question 2 to calculate the area of the largest rectangle that can be inscribed in the region bounded by the graph of y = 6 - 2x2 and the coordinate axes. Hint: this is an optimization problem, so dA/dx = 0. Show transcribed image text
