Constant function

Revision as of 23:52, 3 March 2016 by Mooey5775 (talk | contribs) (Fixed LaTeX error)

A constant function is a function which has a constant output: the value of the function does not depend on the value of its input. Equivalently, a constant function is a function whose range has only a single value. For example, $f(x)=4$ is a constant function, and so is $g(x)=\log_{34} e^{\pi-\frac{1}{2}}$.
