The common ratio refers to the rate of change in an exponential function. In the form given above, the common ratio is "b". For example, in the function f(x) = 2*3^x, the initial value is 2 and the common ratio is 3. video https://cdn.kastatic.org/ka_thumbnails_cache/68028de3-62cf-4e38-887f-4f945cde67cd_1280_720_base.png Initial value & common ratio of exponential functions In an exponential function of the form f(x) = a*b^x, the initial value is usually taken to be the value of f(0), or "a".
