How do I do this? + answers

Classify the shaded value in each table as one of the following. Assume that the shaded value represents a critical point. X - -3 -2 -1 0 1 2 -3 2 3 2 - 1 -6 -13 -2 3 4 3 0 -5 -12 - 1 2 3 2 -1 -6 -13 O -1 0 -1 -4 -9 -16 1 -6 -5 -6 -9 -14 -21 2 -13 -12 -13 -16 -21 -28 3 -22 -21 -22 -25 -30 -37 neither a relative extremum nor a saddle point relative minimum O saddle point O relative maximum X
