For part E, I've 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 doesn't 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) ? I am not sure about the increasing part..
but when graphing it on my calc, it look like 1.521 would work better..
