TopicComposite & Inverse Functions

17 The function f is defined by $$\mathrm { f } ( x ) = | x | + 1 \text { for } x \in \mathbb { R }$$ The function g is defined by $$g ( x ) = \ln x$$ where g has its greatest possible domain. 17
  1. Using set notation, state the range of f 17
  2. State the domain of g
    17
  3. The composite function h is given by $$\mathrm { h } ( x ) = \operatorname { gf } ( x ) \text { for } x \in \mathbb { R }$$ 17
    1. Write down an expression for \(\mathrm { h } ( x )\) in terms of \(x\)
      17
  4. (ii) Determine if h has an inverse. Fully justify your answer.
