Find the local maximum and minimum values of the function f(x) = - x - 36/x using the Second Derivative Test.

Find the open intervals on which the function f (x) -3x- | 4x + 6 is increasing or decreasing. Note: Use the letter U for union. To enter oo, type the word infinity. If the function is never increasing or decreasing, enter NA in the associated response area. increasing decreasing: Find the local maximum and minimum values of the function / (x) - -3x~ | 4 + 6
