Question 307293: find the domain of the function
g(x)=sqrt(5x+5)

type answers in interval notation. Answer by rapaljer(4671) (Show Source):
The restriction here is due to the fact that there is a square root in the function. The RADICAND must be greater than or equal to zero.
That is,

Please see my own website at "www2.seminolestate.edu/rrapalje". Look for the link on my Homepage "MATH IN LIVING COLOR", and look under either Intermediate (Chapter 5) OR College Algebra (Chapter 2).
I also have a video of my own teaching in class a few years ago. To see the videos, look for "Rapalje Videos in Living Color", and see either Intermediate or College Algebra for the topic "Functions, Domain, and Range".
