Question 250803
we need three negative, three positive, and x= 0. We can create a table for this:

x . . . . -3 . . . -2 . . . -1 . . . 0 . . . 1  . . . 2 . . . 3
f(x) . . e^-2 . . e^-3 . . e^-5 . . e^-5 . . e^-6 . . e^-7 . .e^-8.

You should be able to plot the points.

The domain is all reals
The range is Y > 0.
