The equation x squared y minus 15 = 0 represents a relation as it contains ordered pairs (x, y); it may not represent a function because for some x, there could be more than one y.
The given equation is x squared y minus 15 = 0. In terms of mathematics, a relation is any set of ordered pairs (x, y) and a function is a relation with exactly one output y for each input x. The given equation does represent a relation as it has ordered pairs (x, y).
However, it does not represent a function because for some values of x, there could be more than one corresponding y which does not confirm to the definition of a function. This conclusion depends on how x and y are related. If y value is defined by x or the other way around, it could be a function.
