Locate and classify all extrema in the graph. (By classifying the extrema, we mean listing whether each extremum is a relative or absolute maximum or minimum.) Also, locate any stationary points or singular points that are not relative extrema. (Order your answers from smallest to largest x. ) 6 3 -9 -6 -3 X 3 6 9 -3 -6 f has an absolute minimum V at (x, y) = 9.0 X f has a relative minimum vx at (x, y) = -6,3 X f has an absolute maximum v X at (x, y) = 9, - 6 X
