They are terms of an expression which has no solution because it is not an equation.
x2 + 2y - 6x + 8y - 1 = x2 - y2 + 4x + 6y - 1 y2 - 10x + 4y = 0 y(y+4) = 10x It cannot be solved completely because with two variables (x and y) you need two independent equations for a full solution.
No, because there is more than one solution: y2 = x2 y = ±(x2)1/2 y = ±x Because there are multiple solutions for a single value of x, this does not qualify as a function.

y2 + y2 = 2y2
There is no single solution for x2 + y2 = 13, as there are an infinite number of corresponding values that could be plugged in for x and y. x2 + y2 = 13 is a function that describes a circle. The circle would have a center point of 0, 0, and a radius of √13.

To graph y2 = -3x, first solve for y. Doing this results in two solutions: y = √(-3x) and y = -√(-3x) Put the first solution into y1 and the second solution into y2. The two solutions together should form a sideways parabola.
