Question 144975
What is the domain of the composite function G(F(x))? 
f(x) = √x 
G(F(x))=1/√x-4 
G(y)=1/y-4 
the possible answers are
A. x < 0 
B. x &#8804; 4 
C. x &#8805; 0 
D. x > 0 
E. x < 4 
F. All real numbers 
-------------------------
f(x) = &#8730;x 
Domain of f is x>=0
--------------------
G(y)=1/y-4 
Domain of G eliminates 4 from the domain
---------------
G(F(x))=1/&#8730;x-4
Domain of the composite is "All Real numbers >=0 except x=4
