Answer:

A

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

Step-by-step explanation:

Think of the answer choice in a table

  x  |  y

1     |    5

2     |   6

4     |    5

exactly one input (x) has one output (y)

in a function likw this you have to make sure that the x is going to one y.

if not than it is not a function.

(1,2),(1,5)(3,9)        

see the one in this orderd pair goes to 2 and 5 so in is not a function
