In mathematics, the term linear function refers to a function that satisfies the following two properties:
The linear functions may be confused with affine functions. One variable affine functions can be written as . Although affine functions make lines when graphed, they do not satisfy the properties of linearity.

Famous quotes containing the word function:
“Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.”
—Susanne K. Langer (1895–1985)
