<ul><li>In <a href="/facts/Calculus/MEmUTYoz">calculus</a> and related areas, a linear function is a <a href="/facts/Function_(mathematics)/CdReEKCh">function</a> whose <a href="/facts/Graph_of_a_function/htYX0BGX">graph</a> is a <a href="/facts/Straight_line/gJqsr4Gj">straight line</a>, that is, a <a href="/facts/Polynomial_function/Lzak8VVx">polynomial function</a> of <a href="/facts/Polynomial_degree/Bf8vEIhf">degree</a> zero or one. For distinguishing such a linear function from the other concept, the term <i><a href="/facts/Affine_function/BD7yDr10">affine function</a></i> is often used.</li>
