Quadratic functions are functions in which the 2nd power, or square, is the highest to which the unknown quantity or variable is raised.. The function y=x2 or f(x) = x2 is a quadratic function, and is the parent graph for all other quadratic functions. The shortcut to graphing the function f(x) = x2 is to start at the point (0, 0) (the origin) and mark the point, called the vertex. Note that the point (0, 0) is the vertex of the parent function only. In calculus, this point is called a critical point, and some pre-calculus teachers also use that terminology.
