1.If f:R→Rf : \mathbb{R} \to \mathbb{R}f:R→R be defined as f(x)=e2x−e−2x2f(x) = \frac{e^{2x} - e^{-2x}}{2}f(x)=2e2x−e−2x, thena.fff is many-oneb.fff is intoc.f−1(x)=12log(x−x2+1)f^{-1}(x) = \frac{1}{2}\log(x - \sqrt{x^2 + 1})f−1(x)=21log(x−x2+1)d.f−1(x)=12log(x+x2+1)f^{-1}(x) = \frac{1}{2}\log(x + \sqrt{x^2 + 1})f−1(x)=21log(x+x2+1)Login to continueOnly logged in users canattempt or see the solution.
