Which set of ordered pairs does not show y as a function of x? A. {(3,-2); (5,-3); (7,-4); (9,-5)} B. O {(3,-2); (6,-2); (9,-2); (12,-2)} c.{(4, -2); (5,-3); (6,-4); (7,-5)} D.O{(4, -2); (5,-3); (4,-8); (5,-9)}
[tex]\begin{gathered} \text{The option D is correct.} \\ \text{Because here input value 4 and 5 (x-value) both have different different} \\ \text{output value (y-value}) \\ To\text{ show the y as function of x, there must be single output value (y-value)} \\ \text{ from single input(x-value)} \end{gathered}[/tex]
