Dan is absolutely right.  copying and pasting often messes up your exponents.
Your screen shot is fine; it shows the exponents as they should be presented.

Next:  How do you recognize a function?  How do you recognize a non-function?

Graphing helps with this.  The graph of x=y^2 looks like|dw:1456688165312:dw|
