| exponential | Pertaining to exponents; involving variable exponents; as, an exponential expression; exponential calculus; an exponential function. Exponential curve, a curve whose nature is defined by means of an exponential equation. Exponential equation, an equation which contains an exponential quantity, or in which the unknown quantity enters as an exponent. <mathematics> Exponential quantity, a quantity whose exponent is unknown or variable, as a^x. Exponential series, a series derived from the development of exponential equations or quantities. Origin: Cf. F. Exponentiel. Source: Websters Dictionary (01 Mar 1998) |

| exponential decay | <epidemiology> A decline in which the rate of decay is always proportional to the amount of material remaining; the constant of proportionality is the rate constant. (05 Dec 1998) |
| exponential distribution | The time until failure of a process at constant hazard. (05 Mar 2000) |
| exponential growth | <biology> A rate of growth of an organism, a part of an organism, or a population of organisms which, when graphed, produces an exponential or logarithmic curve. Such a rate occurs, for example: during the exponential growth phase, when a population of bacterial (or other) cells divide at a constant rate so that the total number of cells doubles with each division. (09 Oct 1997) |
| exponential phase |
The growth stage where cells undergo their maximum rate of cell division. The exponential phase follows the lag phase, and precedes the linear growth phase. See growth phases. aka logarithmic phase.

| exponential |
denoting a mathematical function in which the variable or variables appear in exponents, e.g., y = ax, where a is a constant and x is a variable.

| exponential d. |
a skewed probability distribution with right tail extending to infinity and having the density function f(x) = λ e-λx for x ≥ 0 and λ > 0. The mean is 1/λ and the variance is (1/λ)2. The mode is at zero and the larger the parameter λ, the more clustered the distribution toward zero. The exponential distribution arises in medicine and reliability as the time to mortality/morbidity or failure; λ is often interpreted as the force of mortality or failure.
