What is the inverse of f ( x ) ? f ( x ) = la1" title="\frac{2}{x - 6}" alt="\frac{2}{x - 6}" align="absmiddle" class="latex-formula">

Answer 1

The inverse of f(x) is (6x + 2)/x.

What is an inverse function?

The inverse function is defined as a function obtained by reversing the given function.

Given that f(x) = 2/(x-6)

To determine the inverse of a function, all you have to do is switch where x and y are and resolve for y.

So after switching x and y,

f(x) = y = 2/(x-6)

becomes

x = 2/(y - 6)

Now, we solve for y regularly.

f(x) = y = 2/(x-6)

Solve for y :

⇒ x(y - 6)  =2

⇒ xy - 6x = 2

⇒ y = (6x + 2)/x

Therefore the inverse of f(x) is (6x + 2)/x
