  == Blatant factual errors and incorrect graph ==  An exponential function is NOT some arbitrary constant to the power of some variable (e.g. ).  Exponential growth uses a specific constant, e. It's of the form:   It MUST use the exponential function (expe to the power of something) to be considered exponential growth.
