Curve Sketching help!! 1. The problem statement, all variables and given/known data http://img21.imageshack.us/img21/7660/54035638.jpg [Broken] 2. Relevant equations 3. The attempt at a solution For part E, ive been sitting on it for the last 2 hours trying to figure out why this is wrong.. i came up with a solution but it doesnt seem to be right.. if solving for f'(x) i get x=6.279 so f'(x) > 0 ==> x<6.279 f'(x) < 0 ==> x>6.279 decreasing (-inf, 6.279)U(6.279, inf) and increasing on (6.279, 0) ? im not sure about the increasing part.. but when graphing it on my calc, it look like 1.521 would work better..
