Piecewise functions.

A Piecewise function is defined as being made up of other functions. Usually there are two functions that make up a Piecewise function and they often come Ina linear format, although there are some exceptions. The two functions are then graphed separately onto the same graph depending on their domains. Two if the most well known Piecewise functions are that of absolute value and the floor function. The absolute value Piecewise functions is made up of the functions y=-x and y=x. The graph itself looks like a linear line from the origin that has been reflected onto both sides, therefore making a V or slanted right angle shape. The floor  function looks like a flight of stairs. The function hasnanninfinite number of pieces so it goes on forever.
