Well, what is
?
Do you want to find the domain of h(x)?
Start with the given expression
Remember you cannot take the square root of a negative value. So that means the argument
must be greater than or equal to zero
Set the inner expression greater than or equal to zero
Add 1 to both sides
Combine like terms on the right side
Divide both sides by 2 to isolate x
So that means x must be greater than or equal to
in order for x to be in the domain
So the domain of h(x) in interval notation is
[

Also, the domain of h(x) in set-builder notation is
