thatswhat i got @Solmyr

- anonymous

well when answering these kind of questions we look at the x-value

- anonymous

srry had to do soomething

- anonymous

ok x is 1 3 5 7

- anonymous

u have to look at the x-value if there is more then one of the same number then to relation is not a function.

- anonymous

i got d actually

- anonymous

correct

- anonymous

because there are two 2's in the x-value
