So I have a function $\displaystyle f(x) = e^{-x^2}$. I want to write this without a negative exponent. How would I do this? I know how to do it with integer exponents, but I'm not sure when they're variables. Thanks!

That's what I thought, but this text says this:

$\displaystyle \frac{x}{e^{x^2}}$

Actually, I'm an idiot, just realised that the function was $\displaystyle xe^{-x^2}$ >_<

That explains why I was confused!
