Constant Function

Concept

Constant Function

A constant function is a linear function whose graph has a slope of 0.0. An example is the function y=2.y=2.

The equation of a constant function can always be written on the form y=b, y=b, where bb is the yy-intercept. Constant functions typically do not have xx-intercepts. The only exception is the function y=0,y=0, which has an infinite number of xx-intercepts.
