The domain of f (x) = 2logx+3 is x > 3.

true.

false.

This is a problem of calculus. So, for getting the domain of this function, we nee to study each term. So, firs of all we have the function log (x). For this function it is true that the domain is:

x > 0

So, there is not other function for this problem. Thus, the answer is false. See the figure below that shows f (x)
