1. Let f (0, ∞)→ R be the function with f(x) = |1 ln x]. Sketch the graph of y = f(x). Give a brief justification (one sentence each) why f is not injective and why f is not surjective. Come up with a subset A of R of your choice such that the function g: A → R with g(x) = 1 In x is injective. No justification needed. Come up with a subset B of R of your choice such that the function h: (0, ∞) → B with h(x) = 1- ln x is surjective. No justification needed.
