http://mathquest.carroll.edu/CarrollActiveCalculus/S_0_2_Exponentials.html Webthe constant ratio is 1/3 because each term is multiplied by 1/3 to make the next term (like dividing by 3) This makes an exponential function (only if the constant ratio is positive) To identify a constant ratio, divide a term by the preceding (previous) term. If the ratio between all terms is the same (constant) it is an exponential function.
