Graphical Behavior

Constant Function

A constant function is a polynomial of degree 0. For example f(x) = 4; any value selected for x will always yield a value of 4 for the y-value. In general, when f(x) = c; any value selected for x will yield c for the y-value. The graph of a constant function will be a horizontal line intersecting the y-axis at the value of c. It is a line with slope equal to zero (m = 0).
