What are the critical values?

Where are the relative extrema, if they exist?

**Steve**, Thursday, November 15, 2012 at 1:45pmcritical values are values in the domain where f'(x) = 0

since f'(x) = 3x^2 + 6x - 1, the critical values would be (-3±2√3)/2

the extrema occur at the critical values.

extrema at x=(-3±√15)/3
