Question

How would I go about finding the domain of
(64-e^(x^2))/(1-e^(64-(x^2)))

Answer 1

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

Answer 2

set the denominator equal to 0 and solve for x

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

nope, it would be

(-infinity,-8) U (-8,8) U (8,infinity)

Answer 7

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

Answer 8

oh right

Answer 9

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