## anonymous one year ago Which of the following lists of ordered pairs is a function? A. (-1, 2), (2, 3), (3, 1), (2, 5) B. (1, 2), (4, 0), (3, 5), (4, 3) C. (2, 5), (3, 6), (2, 1) D. (2, 5), (3, 6), (6, 9)

1. Nnesha

in order to relation become a function x values shouldn't repeat

2. Nnesha

(x,y) first number represent x-coordinate (domain )

3. anonymous

4. Nnesha

(x,y) is a order pair (a point )

8. Nnesha

you don't have to draw it out but you can if u want

9. anonymous

D. (2, 5), (3, 6), (6, 9 so this would be the right answer ?

10. Nnesha

yes right each y values have only one x value so yes x values aren't repeating then yes it's a function

11. anonymous
