Maximizing Area An isosceles triangle has one vertex at the origin and a horizontal base below the x-axis with its endpoints on the curve y = x2 − 16. See the figure. Let (a, b) be the vertex in the fourth quadrant and write the area of the triangle as a function of a. Use a graphing calculator to find the point (a, b) for which the triangle has the maximum possible area.
