Abstract

An algebraic equation in the form y = f(x), such as y = x2 − 2x + 3, is called a Cartesian equation (after the French mathematician Descartes), and a mapping diagram referred to perpendicular axes is the Cartesian graph of the function f(x). Since the value of y is calculated from a given value of x, x is the independent variable and y is the dependent variable.
