is x 2 y 2 10 a function The equation x y 2 is BOTH curves y sqrt x and y sqrt x together These two are individually functions but when you plot them on the same coordinate plane
The rule is that you plug in x and y and must have x 2 y 2 25 be true The domain is important For example if the domain is only x 5 and x 5 then you have a function since it is well defined Best Answer A function is the type of relation that every x value has only one y value paired with it In y x for every value of x there is only one value for y For instance

The answer is the relation x y2 is not a function Please see below for a demonstration and explanation of this Explanation We are given the relation x y2 We are asked to decide if it defines a function If no matter No Because of a function s definition is that for any single y value there exist one and only one x value Here if we put in x 2 we get y 2 4 y 2 So this indicates that this
