What function is y squared equal to x
High school did not learn well, ask the math teacher or know to answer, if you can send a picture


y2=x,
It is equivalent to the parabolic equation when p = 1 / 2 in the parabolic y2 = 2px



Is it a function that the square of x plus the square of Y equals 0?


No. This XY must be 0 to be true
