Best answer

Below is a general shape of e^-x and also e^x side by side for comparison:

as you can see they are just flipped versions of one another as one would expect.

Now, to answer the question why is e^0= 1? Well that is because  any number raised to the power of 0 will equal one:

ie.  x^0 = 1 (where x is any number)

e is just another constant in mathematics, such as pi.

e =  approximately 2.71828

therefore, e^-1 = 2.71828^-1  = 0.3678, which is just a single point or dot.
