I'll get you started... f(x) for any x should give a unique answer... if it does not then your function has no inverse examine f(x) =

Yes, I know what an inverse function is. It's when the dependent and independent variables of a function are interchanged. No, I've never heard of the horizontal line test before.
This site Inverse Functions: Definition / Drawing Inverses explains it well.
