ok i understand (i think) how to figure out if a function is odd or even. in simple terms it if you plug in the opposite of x and if it comes out positive then its even, if it comes out negative then its odd. but! i know this is very simple algebra but I don't remember it anymore

Code: Select all

(-x-1)^3
y = -----------
      (-x+1)^2
how do i simplify this? like i put the power into the -x-1...how? just trying to simplify it to see if it comes out negative then i can see if its odd or even!

next question:

the discontinuities of the original function (see first post) would be

x=1 AND x=-1 right? or was my teacher giving me a bad translation when she said discontinuities, is there more than 1?

same thing with the "find the zeros" - is there only 1 zero or more than 1?
