The standard form of an exponential function looks something like this:

 a(b)^{cx-h}+k 

• a: Vertical stretch/compression
• c Horizontal stretch/compression
• h: Horizontal translation left or right
• k: Vertical translation up or down

Without stretch:

 a^{x-b}+c 

A negative exponent is the equivalent of 1/x, EG

 x^{-2} = \frac{1}{x^2} 

An equation in the base form 2^x will have an asymptote of y = 0.

Putting a negative in front of something like 2^x flips it over the x axis (-2^x). Putting a negative in front of the exponent (2^{-x}) flips it over the y axis.
