Question 62554
{{{g(x)=sqrt(x+2)}}}
The domain is what x is allowed to be.  The inside of even roots are only allowed to be greater than or equal to 0, within the real numbers.
{{{x+2>=0}}}
{{{x+2-2>=0-2}}}
{{{x>=-2}}}
X can be anything as long as it's greater than or equal to 0.
The domain is:
set builder: {x|x>=-2}
interval notation: [-2,infinity)
Happy Calculating!!!!
