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.

Is x2-y2 plus 49 equals 0 a function?
Yes
Equation of director circle of the circle x2 plus y2 equals r2 is?
x2 + y2 = 2r2
Convert x2 plus y2 equals 2x?
What do you want to convert it to? x2 + y2 = 2x If you want to solve for y: x2 + y2 = 2x ∴ y2 = 2x - x2 ∴ y = (2x - x2)1/2 If you want to solve for x: x2 + y2 = 2x ∴ x2 - 2x = -y2 ∴ x2 - 2x + 1 = 1 - y2 ∴ (x - 1)2 = 1 - y2 ∴ x - 1 = ±(1 - y2)1/2 ∴ x = 1 ± (1 - y2)1/2
