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}}
