#2**+2 **

"Domain" is defined as the x values covered by the graph

Notice that the least x value is -6

And the arrow indicates that the function covers all the x values from here to infinity

So....the domain is just all x values from -6 to infinity including x = -6

In math terms, this can be represented as

x ≥ -6

Just as Emine has found.....!!!

Does that make sense, RP ???
