Question

How do you find domains for functions?

Answer 1

$$
\sqrt{x+5}\over x-1
$$
Is this the problem?

Or is it
$$
\sqrt{x+5\over x-1}
$$

Answer 2

Its the first one you wrote.

Answer 3

I think it would be x can't equal 1 and x has to be greater than or equal to -5.

Answer 4

Ok.

To find the domain, we don't allow two things
1) The denominator can NOT be zero
2) Anything under the square root can NOT be negative

Your answer is perfect!
