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

Umm, how about I just post the thing that has all these on them

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

\[f(x)=\sqrt{x+1} \,\,\text {or} f(x)=\sqrt{x}+1?\]

That's what I thought cinar

that was a typo. sorry you guys!

so 1 is not under the square root?

hugsandkissesBest ResponseYou've already chosen the best response.0
it is. x+1 are under the square root

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

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