ok ill just post what i sent to esuolohim here

so i need to be able to tell if a graph is gonna be symmetrical along the x y or origin some shit

so here's the equation thing y=x/x(squared)+1

so thats y equals x divided by x squared and +1. x squared and plus 1 are both under the division sign.

i dont understand how changing y and the x's into negatives ends up equaling the same thing as if it were positive

the only way i can think to solve it is to do a graph which i dont want to do.
oooh. would i just fine a number that works like put 0 in for x, calculate it get an answer. Then make it negative and do the same thing and i should get the same number?

the other ones i can tell just by looking though so i dunno if im supposed to do all of that ;/
