The function  f(x,y){“version”:”1.1″,”math”:”f(x,y)”} has a gradient vector equal to the zero vector at five separate points. Use the given table of values to classify each point as the location of a local maximum, local minimum, saddle point, or a point where the second derivative test fails. (Selections can be used more than once; all selections need not be used.)
