Article 11 — Appendix A.24^ — power functionCategory. Mathematics. Abstract. Power: 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. DefinitionPower function is the function of kind x^{a}2. GraphPower function domain depends on power a, but it is always defined for positive real halfaxis (0, +∞). Parabola graph for a = 2 is depicted below — fig. 1. Fig. 1. Graph of the power function y = x^{2}.Function codomain as well depends on power a, but it always includes positive half of the real axis (0, +∞). 3. IdentitiesNegative power: x^{−a} = 1 /x^{a}Power sum and difference: x^{a + b} = x^{a} x^{b}x^{a − b} = x^{a}/x^{b} Power product: x^{ab} = (x^{a})^{b}4.
