If x x is the independent variable and y y is the dependent variable then x y2 x y 2 is not a function It s a tilted parabola and fails the vertical line test And you give a good example If x 1 x 1 then we have two y y values 1 1 and 1 1 So one point on the x x axis maps two points to the y y axis 1 Answer. Alan P. Aug 1, 2015. x2 +y2 = 9 is not a function. Explanation: In order for an equation to represent a function any single value of x must have at most one corresponding value of y which satisfies the equation. For x2 + y2 = 9. XXXX if (for example) x = 0. XXXX there are two values for y (namely +3 and −3) which satisfy the equation.
