An explicit definition of a function f gives an algorithmic procedure, usually given by an algebraic formula, that produces the output (dependent variable) of f for a given input (independent variable); for example, f(x) = x2.
1 (of a number x) a number whose logarithm is a times the logarithm of x (and is called the a th power of x). Symbolically, y = xa is a number that satisfies the equation log y = a log x.  the exponent of an expression, as a in xa.
