Objective [1.6]-Notes Know and understand the rules of representing a function in a Cartesian plots including relevant vocabulary. Understand when a Cartesian plot is indicating a relationship is not functional (Note: the vertical line test for relationships that are functional is covered in the book as well as in objective 1.3 about restricted domains) Rene Descartes is credited with defining a system to represent the precise relative location of objects in space on a piece of paper b y means of “spatial coordinates”. Later he realized that algebraic functions could be also be represented on the same “Cartesian” coordinate system with pairs of spatial coordinates replaced by ordered pairs of a function. So first one has to know about how the basic Cartesian coordinate system is defined and then the few rules about representing functions. Here a list of construction rules, comments and suggestions as relates to representing ordered pairs of a function on a Cartesian plot. 1. Construct two perpendicular straight lines. These will be called axes. Their intersection is called the origin and has the ordered pair (0,0). Orient the two axes so one is horizontal on the page and the other vertical. 2.
