Question

LOGS

Answer 1

\(f(x)=\log(x+3)-1\)

Answer 2

at first, as far as the domain goes, you can only take a log of something that is greater than 0.

In this case, you are taking log of \(x+3\), and thus \(x+3\) has to be greater than 0.

all \(x\) values that satisfy \(x+3>0\) are in the domain x. (of course x\(\in {\bf R}\))

Answer 3

so how can I include that in the problem?

Answer 4

what do you mean?

Answer 5

we are finding the domain - that is the first part of the task. So now we (almost) found the domain.

Can you give me an interval for the domain?
