Which of the following lists of ordered pairs is a function?

Answer: B. (2,5) , (3,6) , (6,9)
Step-by-step explanation:
In ordered pair , the x coordinate shows the input value and the y-coordinate shows the output value.
In the given lists only list B is representing a function since each input corresponds to a unique output.
In list A. , 2 corresponds to two different values i.e. 5 and 1 .
Thus its not a function.
In list C., 2 corresponds to two different values i.e. 5 and 3 .
Thus its not a function.
In list D. 4 corresponds to two different values i.e. 0 and 3 .
Thus its not a function.
