You can put this solution on YOUR website!
What is the Domain for these functions:
g(x)= 2x+1/x-3
Domain: all Real Numbers except x=3
------------------------
h(x)=3x^2+5x-3
Domain: all Real Numbers
-------------------------
l(x)=2x+3
Domain: all Real Numbers
----------------
m(x)=3/x^2+7
Domain: all Real numbers if your problem is 3/(x^2+7)
Domain: all Real numbers except zero if your problem is [3/(x^2)] + 7
------------------
