**Marth**, Thursday, July 16, 2009 at 5:08pmStart with the base function: y=e^x.

The range of y=e^x is (0, infinity).

If you have y=e^-x, that flips the function over the y axis, which does not change the range.

Now factor in the -2. That shifts the function down, so subtract 2 from the range: (-2, infinity)

e^x exists for all real values of x, so e^-x does also.

Therefore, the domain is (-infinity, infinity)
