**michael**, Monday, October 26, 2009 at 12:43am1. P&prime&prime(R)=0

->gives you the points at which the slope of P(R) changes from increasing to decreasing or vice versa.

2. Plug in a number between the intervals back into P&prime&prime(R)

-> for example if you found:

R= -1 and R = 4

plug in 0 or 1 or 2 or 3 into P&prime&prime if its positive then the slopes are increasing on the interval from (-1, 4)
