Question

What's the inverse

Answer 1

**What have you tried and where are you stuck?**

Also, Is that supposed to be:

> f(x) = x^2 - 6x

or is the formatting in the post correct?

If the function *is* meant to be a quadratic then the inverse (and whether or not one exists) will depend on the intended domain and codomain. For example, if f is defined as a function from the Reals to the Reals, it has no inverse.

Answer 2

This is learn math. What have you done so far?

Answer 3

Use the fact that f(f^(-1)(x))=x

Where f^(-1)(x)=inverse of f(x)

(You will also need to complete the square)

Edit:
(I just realized that there is no inverse function)

Answer 5

The key is to switch the x and y, then solve for y.

To get you started:

f(x) can also be written as y

So, y = x\^2 - 6x

Now switch the x and y

x = y\^2 - 6y

How would you solve for y?

Complete the square.
