    \[\frac{ 64- e ^{x ^{2}}}{ 1-e ^{64-x ^{2}}}\]

    set the denominator equal to 0 and solve for x

    I did that and I got +/- 8, but that is not the right answer apparently

    huh, that's odd, did you write your domain as x =/= 8 and x =/= -8

    in interval notation would you right this as (-8,8)?

    nope, it would be (-infinity,-8) U (-8,8) U (8,infinity)

    remember to include values that are less than -8 and greater than 8

    Cuz I graphed this on a graphing calculator, and it didnt show the graph x<-8 and x>8. so I got confused
