The easiest type of function to consider is a linear function.
Remember y f x so lets graph y x 2 which is a square function parabola This then is the graph for the piecewise function given above. Quadratic functions and the properties of their graphs such as vertex and x and y intercepts are explored interactively using an applet. A function is uniquely represented by the set of all pairs x f x called the graph of the function. When the powers of x can be any real number the result is known as an algebraic function.
