If you take the square root of a negative number, it is not a member of the real number system. x cannot be negative. The domain of f(x) is \[[0,\infty)\]

^not true, x can be negative

Oh i was going by the original post. Didn't see the updated one.

That's what I thought cinar

f(x)= √x+1

rickjbr Group TitleBest ResponseYou've already chosen the best response.2
so 1 is not under the square root?
 2 years ago

hugsandkisses Group TitleBest ResponseYou've already chosen the best response.0
it is. x+1 are under the square root
 2 years ago

rickjbr Group TitleBest ResponseYou've already chosen the best response.2
OK, use parentheses next time \[\sqrt{x+1}>0, x>=1\] Domain is \[[1,\infty)\]
 2 years ago

cinar Group TitleBest ResponseYou've already chosen the best response.1
then domain is [1,infinite) range is [0, infinite)
