find the domain of and explain if realnumbers or real numbers except ?
g(x)=2x+1/x-7
Domain: All Real Numbers except x = 7
-------------------------------------------------

g(x)=2^2-7x+1/x
All Real Numbers except x = 0
-------------------------------------------

h(x)=3x^2+5x-3
All Real Numbers
==================================
