2)all real numbers less than 0
3)all real number greater than 0
4)all real numbers including 2 and 6

Answer 1

The answer to your question is number 1) all real numbers.

Explanation:

The Domain is all the set of numbers the x-axis could have.

In the graph, we notice a line that goes from zero to six, we could think that the domain is that interval but as the line has arrows, we can think that the line grows up in both senses, then the domain must be all real numbers.
