which set of ordered pairs does not represent a function?



(4,1), (6,2), (7,5), (9,2)

(0,5), (1,7), (2,9), (3,11)

(-2,5), (0,2), (9,-6), (8,7)

(5,5), (6,10), (10,15), (5,20)​

Remember that

A relation between x and y represent a function if for one value of x there is only one value of y

so

Verify each set of ordered pairs

N 1) ------> represent a function

N 2) ----> represent a function

N 3) ----> represent a function

N 4) ----> Not represent a function, because for x=5, y=5 and y=20

therefore

the set (5,5), (6,10), (10,15), (5,20)​ not represent a function
