Article 11 — Appendix A.20exp — exponential functionCategory. Mathematics. Abstract. Exponent: definition, graph, properties and identities. References. This article is a part of scientific calculator LiL, scientific calculator LiX, scientific calculator LiLc and scientific calculator LiXc products. 1. DefinitionExponential function is the function of kind e^{x}where constant e is selected so that slope of the function at point x = 0 is 45°. 2. GraphExponential function is defined everywhere on real axis. Its graph is depicted below — fig. 1. Fig. 1. Graph of the exponential function y = e^{x}.Function codomain is positive half of the real axis: (0, +∞). 3. IdentitiesBy definition: e^{lnx} ≡ xNegative argument: e^{−x} = 1 /e^{x}Sum and difference of arguments: e^{x + y} = e^{x} e^{y}e^{x − y} = e^{x}/e^{y} Product of arguments: e^{xy} = (e^{x})^{y}Base change: a^{x} = e^{x lna}4.
