Question: 1) Find the critical point(s) for f(x) = x - 8x3 +2 . X - Coordinates only. 6pt 2) For f(x) = x - 6x3

1) Find the critical point(s) for f(x) = x" - 8x3 +2 . X - Coordinates only. 6pt 2) For f(x) = x - 6x3 +15 find the intervals of increase or decrease. Show your findings using a sign chart and present your answer in interval form. 6pt 3) Find the value of x for which the mean value theorem is satisfied: f(x) = x' - x over [-1,2] f' (x) - f(b) - f(a) b - a
