Just (c) and (d). Show all work

2. (11 points) Find the critical points of the following functions. (a) (1 point) f($) = .132 63: + 7 (b) [2 points) Mt) = 6t2 t3 For the next two) use the product rule together with the chain rule and factor out the greatest common factor. Then the rest of the factoring should be clear. (c) (4 points) h(s) = 3(4 s)3 (d) (4 pointS) M3!) = ('y - 1W3; - 3)2
