Fourier Transform - Scaling Property

[snesnerd]

Homework Statement

Find the Fourier transform of (1/p)e^{[(-pi*x^2)/p^2]} for any p > 0

Homework Equations

The Fourier transform of e^{-pi*x^2} is e^{-pi*u^2}.

The scaling property is given to be f(px) ----> (1/p)f(u/p)

The Attempt at a Solution

Using the information above, I got p*e^{(-pi*u^2)/p}.
On another attempt, I got e^{-pi*p^2 * u^2}.
I am not sure if either one of these is correct. I have a hard time following the scaling property.
