Sorry, I have no idea what a variation function is. Are you from the US?

Right, no I'm from England. We use different terminology is all. We call direct variation direct proportion. Or at least, I've never heard direct variation anyway. Direct variation is basically when all the x values are multiplied by the same number to get the y value. On table 4 you multiply the first value by 3, the second by 4 and the third by 5 so that isn't direct variation. On the third table, you add 3 each time so you can't be multiplying by the same value. On the second table you multiply the first x value by three and not the second or the third so that isn't either. However on the first table you multiply 6 by 1.3333 to get 8 and you multiply 9 by 1.3333 to get 12 and 12 by 1.33333 to get 16. So the first table is Direct Variation as you are multiplying each x value by 1 and a third.

A, the first one :P cause each of the x values is multiplied by the same value.
