1. Find the critical numbers of the function f(x) = 2x3 + 2:2 + 23 2. Find the absolute Inaximmn and absolute minimum value of f[rr} = 12 + 42: 2:2 on [01 5] 3. Verify that the function satises the hypotheses of the Mean Value Theorem on the given interval. Then nd all numbers 0 that satisfy the conclusion of the Mean Value Theorem: x) = 1/2: on [1, 3]
