there is only one value of y for every x
so
it is a function (a parabola in fact)
The inverse of this however is NOT a function
Is y=3x^2-2 a function?
my guess is NO

I don't understand. so is it or is it not a function
It IS a function ! (I said that)
Just watch out if you are asked for the inverse next.
okay thank you I don't know what an inverse is lol
Oh, sorry, assumed that if you were deciding what was a function you also were doing inverses of functions. You will be :)
