1. Determine whether Rolle's Theorem applies to the following functions on the given interval. If so, find the point(s) that are guaranteed to exist by Rolle's Theorem. f(x)= x' -2x2 -8x [-2,4] ((x)= x -x' -5x -3 [-1,3] 2. Determine whether the Mean Value Theorem applies to the following functions on the given interval. If so, find the point(s) that are guaranteed to exist by the Mean Value Theorem. f (x ) = * [-1,2] x+2 f(x)=x+_ [13] X
