Exponential decay — A quantity undergoing exponential decay. Larger decay constants make the quantity vanish much more rapidly. This plot shows decay for decay constants of 25, 5, 1, 1/5, and 1/25 for x from 0 to 5. A quantity is said to be subject to exponential… … Wikipedia
exponential function — Math. 1. the function y = ex. 2. any function of the form y = bax, where a and b are positive constants. 3. any function in which a variable appears as an exponent and may also appear as a base, as y = x2x. [1890 95] * * * In mathematics, a… … Universalium
