. What is (2,00)?. Is that supposed to be

If so, I am sorry, no. You have the infinity part correct. The 2 is not right.

In order to be in the domain, you can not have a negative inside the radical. That results in complex numbers and they are not part of the real domain.

If you solve 3x+2>0, then you can find your domain.
