Question

What is the domain of the function f(x)= 1/3x+2

Answer 1

The answer is the last one

x≥-6

I hope this helps, and God bless <3

Answer 2

If it is 1/(3x+2), 3x+2≠0 =>x≠-2/3, the domain is all real number except -2/3
if it is 1/(3x)+2, 3x≠0, x≠0, the domain is all real number except 0

It is hard to tell from your equation what the demonstrator is.
