Of special interest are relations where every \(x\)-value corresponds to exactly one \(y\)-value. A relation is established between two sets when an object from one set is related to one object from another set, resulting in the formation of ordered pairs. This system is often called the Cartesian coordinate system8, named after the French mathematician Ren Descartes (15961650). <> Typically, the coordinates are related by a rule expressed using an algebraic equation.

If you're looking for a quick delivery, we've got you covered. Add another ordered pair to this relation that would make this not a function anymore. \(g (2) = 4, g (1) = 3, g (0) = 4\), 9. Now consider set A to be the students and B to be the sections. The minimum \(y\)-value represented on the graph is \(0\); thus, the range is \([0,)\). Then the student identifies the domain and range of each example. Recall that when evaluating, it is a best practice to begin by replacing the variables with parentheses and then substitute the appropriate values. {(3,2), (1, -1), (2, -4), (3, -9), (4, -16)} 4. 2.
