Vocabulary
  • Exponential Function has the form y abx,
    where a ? 0 and the base b is a positive number
    other than 1.
  • If a gt 0 and b gt 1, then the function y abx is
    an Exponential Growth Function, and b is called
    the Growth Factor
  • Exponential Decay Function has the form y
    abx, where a gt 0 and
  • 0 lt b lt 1 (this means b is a fraction)
