Find the absolute minimum and absolute maximum of Remaining time: f(x, y) = 18 – 8x+9y on the closed triangular region with vertices (0, 0), (9,0) and (9, 12). List the minimum/maximum values as well as the point(s) at which they occur. If a min or max occurs at multiple points separate the points with commas.
