Single-Valued Function
(redirected from Single-valued)

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.
single-valued function [¦siŋ·gəl ‚val·yüd ′fəŋk·shən]
(mathematics)
A function for which exactly one point in the range corresponds to each point in the domain; a function that associates to each value of the independent variable exactly one value of the dependent variable. Also known as one-valued function.

Single-Valued Function 

a function that maps each value of the independent variable for which it is defined to just one value of the dependent variable—in contrast to a multiple-valued function. For example, f(x) = x2 is a single-valued function, while Single-valued Function is not because to each value of x other than zero there correspond two values of f(x), which differ in sign.
