**Reiny**, Wednesday, April 22, 2009 at 11:49amIn a function, for any given value of x, there can be only one value of y

since all the values of x are different, the points given do form a function.

had there been another point such as (2,3)

for the given value of x=2 there would have been 2 different values of y, namely 0 and 3

thus it would NOT be a function.

BTW, as to my reply to you from a previous post, why don't you just substitute the given values in your inequation, if it works ... ?
