^ power function
Abstract. Power: definition, graph, properties and identities.
Power function is the function of kindxa
Power function domain depends on power a, but it is always defined for positive real half-axis (0, +∞). Parabola graph for a = 2 is depicted below — fig. 1.Fig. 1. Graph of the power function y = x2.
Function codomain as well depends on power a, but it always includes positive half of the real axis (0, +∞).
Negative power:x−a = 1 /xa
Power sum and difference:xa + b = xa xb
xa − b = xa/xb
Power product:xab = (xa)b
Power function ^ is supported in:
Power function of the complex argument ^ is supported in:
