(C) For a function $f: A 	o B$ to have an inverse,it must be a bijection,which means it must be both one-to-one (injective) and onto (surjective). $A$ function that is strictly monotonic (either strictly increasing or strictly decreasing) is always one-to-one. If a function is continuous and strictly monotonic on its domain,it maps its domain to its range in a one-to-one manner,ensuring the existence of an inverse function $f^{-1}$.

$A$ condition for a function $y = f(x)$ to have an inverse is that it should be

Show that $f:[-1,1] \rightarrow R$,given by $f(x)=\frac{x}{x+2}$ is one-one. Find the inverse of the function $f:[-1,1] \rightarrow \text{Range } f$.

Let $f:(0,1) \rightarrow R$ be defined by $f(x)=\frac{b-x}{1-b x},$ where $b$ is a constant such that $0 < b < 1$. Then

Let $f(x)=(x+1)^2-1$ for $x \geq -1$.
Statement-$1$: $S=\{x:f(x)=f^{-1}(x)\}=\{0, -1\}$
