9.2. Functions as Graphs www.ck12.orgTABLE 9.2:rJ(r) = 2r0 2(0) = 01 2(1) = 22 2(2) = 43 2(3) = 64 2(4) = 85 2(5) = 106 2(6) = 12The green dots represent the combination of (r,J(r)). The dots are not connected because the domain of this functionis all whole numbers. By connecting the points we are indicating that all values between the ordered pairs are alsosolutions to this function. Can Joseph ride 2 1 2rides? Of course not! Therefore, we leave this situation as a scatterplot.Example 2: Graph the function that has the following table of values.Side of the Square 0 1 2 3 4Area of the Square 0 1 4 9 16Solution: The table gives us five sets of coordinate points:(0, 0), (1, 1), (2, 4), (3, 9), (4, 16).172
