Answer:
The answer is option C) 8
Step-by-step explanation:
Given that ,
[tex]f(x) = \sqrt{3x}[/tex] and [tex]g(x) = \frac{1}{x-6}[/tex]
f °g means replace the value of x in f(x) by function g(x). In above case as follows,
[tex]f °g = \sqrt{3g(x)} = \sqrt{\frac{3}{x-6} }[/tex]
for the domain of the above function to be defined,
[tex]\frac{3}{x-6}[/tex] > 0 , which means x > 6.
(at 6 function is not defined, indeterminant)
thus, in the above options only 8 is >6.
