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.
