#1 g(x)=x+8/X^2+9X
#2 f(x)=9x/square root of x+4

find the domain
#1 g(x)= (x+8)/(X^2+9X)
Factor:
g(x) = (x+8)/[x(x+9)]
The denominator cannot be zero.
Domain: All Real Numbers except x = 0 and x = -9
=====================================================
#2 f(x)= (9x)/sqrt(x+4)
---
The denominator must be positive.
Domain: All Real numbers greater than -4.
