I'm having trouble sketching the curve f(x) = e^x^-2 could someone please help me get started? I know the steps, but I don't know how to solve for the x to find the zeros or critical values, I also don't even know the domain of this function. I'm sorry if this isn't very clear - I'm a bit panicky right now. I'm under a strict time restraint, so if you could please help me out ASAP, it would be very much appreciated!

Exponentials have zeros when translated or composed with (some) other functions (which isn't the case with this function which is probably what Iruka mean - but I thought I'd point it out).

If you don't recall how to use calculus to find critical points, remember you take the derivative of the function, then find the zeros of the derivative... but you might get a strange result in this case. ;)

Iruka: why have you deleted every post you've made? A lot of them are very helpful.

Graph e^x^2, then reciprocalise it.
