Linear function (calculus)
Polynomial function of degree at most one / From Wikipedia, the free encyclopedia
Not to be confused with linear functional or linear map.
In calculus and related areas of mathematics, a linear function from the real numbers to the real numbers is a function whose graph (in Cartesian coordinates) is a non-vertical line in the plane.[1] The characteristic property of linear functions is that when the input variable is changed, the change in the output is proportional to the change in the input.
