Determine whether each equation defines y as a function of x. X = Y^2
In this case, no. You can rearrange it to be the case, but as given, "X is a function of y"
Well, no, that's not correct. But again, that's not what the question is actually asking.
How exactly do you tell is Y is a function of x
You don't need to do ANY of that.....
Please look at the question.
i would guess no because y isnt by itself..correct?
It's not asking you to FIND y in terms of x, simply to say whether, as given, it is or not. In this case ...it is not. If "y" was "in terms of x" , y would be by itself y = something....
my bad. I misunderstood
...and within that "something", there would be an "x" in there.
