Find the domain of $f(x)=\ln(3x+2)$
I can find domain, but is it the same for a $\log$ function? And also, do I have to rid the equation of the $\ln$ before I can find the domain? I'm really confused as to how to start out this problem. Please help.
Edit: I got the answer and now I ask a question (irrelevant to my problem but I am curious), why does the real portion of $f(x)=\log x$ resemble the graph of a square root function. In a sense of, starting at a single point and going in two directions: up/down & left/right.
