Question 206433
g(x) = (2x+1)/(x-7). The domain is all values of x that make an output (y) possible. All values of X are in the domain, except when the equation is undefined. The rational expression will be undefined when you divide by 0. As such, x-7 is not equal to 0. Therefore, x is not equal to 7.


So your domain is D={x|x is not equal to 7} ... or (- infinity,7) U (7, infinity).
