Please only choose if you are familiar with the he topic. Just question 2

100% & x +1 1. Consider the function h(x) = In x - a) Show that h'(x) = 1-x2 b) Determine an equation for the tangent to h at x = -2. 2. Using the definitions of continuity and differentiability and proper notation, justify whether g(x) is continuous and differentiable at x = -1 or it is not. x S -1 g(x) = 1 x-1 -1
