The equation x 2 y 2 1 describes a relation but not a function A relation between x and y is a set of pairs x y An equation in variables x y always describes a relation namely the set of pairs of values x y which satisfy the equation One or more functions can be implied by an equation but no equation is itself a function The equation x 2 y 2 1 which relates the variables x and y implies two functions of x those whose graphs are the top and bottom halves of the circle one such function is x 1 x 2 two functions of y those whose graphs are the left and

y 2 1 x 2 Longrightarrow y pm sqrt 1 x 2 and you choose the expression with the plus or with the minus then both of them represent the explicit formula of a real one variable function X2 y2 1 does not describe a function because there exist valid values of x for which more than one value of y make the equation true

Hence for y x2 1 it is a function In support of Constantinos contribution Pick any 1 value for x If that 1 value of x relates to only 1 value of y then it is a function The formal Definition of a Function is A function relates each element of a set with exactly one element of another set Hence for y x 2 1 it is a function The set of points satisfying x 2 y 2 1 is a relation in order to say something is injective or surjective you must be very precise specifying the domain the range and in particular you need a function

X 2 y 2 4 is actually the equation for a circle with center at the origin and a radius of 2 Try graphing it by hand by choosing x 0 2 and 2 to get four points on the circle Unless they specify that X Does not equal to one then this isn t a function It s an equation which defines y as a function of x but the function in question is y f x 25 x 2 Similarly x 2 y 2 25 can define y as a function of x if you make a choice of sign for y either y sqrt 25 x 2 or y sqrt 25 x 2

The relation is a function Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor Under that condition the relation is equivalent to y sqrt 36 x 2 and there is no pm Each value of x in 6 6 corresponds to exactly one value of y So the relation here makes y a function of x
