i got it can not equal 8 so would my answer be D?

OpenStudy (anonymous):

x > 0 All real numbers x ≥ -3, x ≠ 2 x ≠ -8, x ≠ -3, x ≠ 2

what values make the denominator zero?

OpenStudy (anonymous):

-8 and 2 @jim_thompson5910

jimthompson5910 (jim_thompson5910):

those values must be excluded from the domain to avoid division by zero errors

jimthompson5910 (jim_thompson5910):

now you must solve x+3 >=0 to make sure that the radicand is never negative

OpenStudy (anonymous):

in which class are you i am of 10 so i am unable

OpenStudy (anonymous):

so i was right? it would be D?

jimthompson5910 (jim_thompson5910):

solve x+3 >=0 to get ???

OpenStudy (anonymous):

3

OpenStudy (anonymous):

-3 my bad

jimthompson5910 (jim_thompson5910):

x >= -3 is also part of the domain

OpenStudy (anonymous):
