Find the inverse of f(x)=2x-1

solong [7]

${ \qquad\qquad\huge\underline{{\sf Answer}}}$

Let's find the inverse of given function ~

$\qquad \sf \dashrightarrow \: f(x) = 2x - 1$

$\qquad \sf \dashrightarrow \: 2x = f(x) + 1$

$\qquad \sf \dashrightarrow \: x = \cfrac{f(x) + 1}{2}$

[ now, replace f(x) and x with $\sf{ {f}^{-1}(x)}$ ]

$\qquad \sf \dashrightarrow \: f {}^{ - 1} (x) = \cfrac{x + 1}{2}$

That's the required inverse function ~
