## anonymous one year ago How would I go about finding the domain of (64-e^(x^2))/(1-e^(64-(x^2)))

1. anonymous

$\frac{ 64- e ^{x ^{2}}}{ 1-e ^{64-x ^{2}}}$

2. Vocaloid

set the denominator equal to 0 and solve for x

3. anonymous

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

4. Vocaloid

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

5. anonymous

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

6. Vocaloid

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

7. Vocaloid

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

8. anonymous

oh right

9. anonymous

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