For y = x^2, both x and -x equal to the save value of y.

For example: 2^2 = -2^2 = 4.

For the y = sqrt(x), for every positive value of x, there is positive and negative value of y.

For example: sqrt(4) = -2 = 2.

    I guess I have no idea how the math symbols are supposed to relate to sexual orientation. Can you help with that part?

    Also, IIRC square root of 4 has only one answer: 2, but negative 2 squared is equal to 4. The functions are asymmetric that way? Is that incorrect? This is all from vague memories of high school and college math.

    Does the square root function always give a positive and negative answer? And we in society just kind of forgot about the negative one?

    the joke only really works for straight being straight and gay being "not straight" but also everything is above the y axis.

    The bisexual one is funny because it doesn't really make sense, it's the "broken rule of three" - where the last one doesn't match the first two, and then the fourth one is just a pun of sorts

    The square root function only has a single answer for every x. This is intentional. The technical definition of function means there can only be a single y value for every x value. Of course, there are situations where you need to consider the positive and negative square root, and that's why the quadratic equation has the ± symbol.
