Identify the x- intercepts of the graphed function.

a. none

b. -1 and 1

it seems to obviously be 1 and -1, but on the previous question, the increasing intervals were listed as (-1, 0) u (1, infinity), suggesting that -1 and 1 are not included points of the function. would it still be -1 and 1?

edit: the intercepts are indeed -1 and 1, the correct answer is b.
