1.Let f:R→Rf: \mathbb{R} \to \mathbb{R}f:R→R be defined as f(x)=x−1f(x) = x-1f(x)=x−1 and g:R−{1,−1}→Rg: \mathbb{R} - \{1, -1\} \to \mathbb{R}g:R−{1,−1}→R be defined as g(x)=x2x2−1g(x) = \frac{x^2}{x^2-1}g(x)=x2−1x2. Then the function f∘gf \circ gf∘g is:Login to continueOnly logged in users canattempt or see the solution.
