Please help with both!!

Instructions: Show all your work for each question. You may use a calculator unless otherwise noted on a particular question. You may use derivative rules unless otherwise noted on a particular problem. All problems must be solved using the calculus techniques taught in this course. Each problem is worth 5 points. Problem 1 Use the Second Derivative Test to find all relative extrema for the function h(t) = 2:3 3t2 12: + 1. Problem 2 Find the absolute extrema for the function f on the interval [0,4]. x x2+2 f(x) =
