A relation contains the ordered pairs (3,8) (6,10) (9,12) and (a, b). For which value of a and b is the relation a function

Step-by-step explanation:

(3,8) (6,10) (9,12) (a, b)

I dont see any answer choices, and there can be several answers ... but I will try to explain

A function will not have any repeating x values ... it can have repeating y values, just not the x ones ... so all ur x's have to be different ... and it doesn't matter what ur y is.

so the answer to this is:

(x, y)

ur y can be any number

ur x can be anything but : 3,6, or 9 ... so as long as ur x is not 3,6, or 9, then it will be a function
