Curve Sketching: Exponential Functions

I'm really having trouble sketching the following curve:

y = e^x^-2

I need help

- finding the x and y intercepts

- how to find if there are any asymptotes

- how to find the critical values for the intervals of inc/dec and concavity

If you could tell me anything, or just start me in the right direction, that would be very helpful. I don't understand the exponential/logarithmic functions very well but my assignment is due in two days and my teacher never gave me an example on how to do it.

Please help!
