F(x)= x+28/x-7 for inverse functions

ioda

The inverse function of the given function is $\mathbf{= \dfrac{28+7x}{x-1}}$

<h3>What is the inverse of a function?</h3>

A function g is the inverse of a function f, if and only if the values of y= f(x), x = g(y).

From the formula given:

$\mathbf{y=f(x) = \dfrac{x+28}{x-7}}$

Let's substitute x with y;

$\mathbf{y= \dfrac{x+28}{x-7}}$

$\mathbf{x=\dfrac{y+28}{y-7}}$

Solve for y;

$\mathbf{= \dfrac{28+7x}{x-1}}$
