SOLUTION: For f(x) = -x^3 + 12x, there is a local maximum value of 16 at 2. Determine the local minimum value.

Question 1208051: For f(x) = -x^3 + 12x, there is a local maximum value of 16 at 2. Determine the local minimum value.

The function is a polynomial with only odd powers, so it is an odd function.

The graph of an odd function is symmetrical with the origin. So, if there is a local maximum at (2,16), there is a local minimum at (-2,-16).

ANSWER: local minimum -16 at x=-2
