High Quality Content by WIKIPEDIA articles! In mathematics, value commonly refers to the 'output' of a function. In the most basic case, that of unary, single-valued functions, there is one input (the argument) and one output (the value of the function). Example: If the function f is defined by prescribing that f(x) = 2x2 3x + 1 for each real number x, then the input 3 will yield the function value 10 (since indeed 2 · 32 3 · 3 + 1 = 10). The function f of the example is real-valued, since each and every possible function value is real. On the other hand, it is not injective, since different inputs may yield the same value; e.g., f( 1.5) = 10, too. In some contexts, for convenience, functions may be considered to have several arguments and/or several values; also cf. the discussion in the article function. However, strictly seen, this is not an extension, since such functions may be considered as having single families and/or sets as input or output. Value is also used in other senses, e.g., to specify a certain instance of a variable.
