Find the domain of the function.

And this is the graph

This one is similar to the one I just worked

Basically, 6-3x has to be greater than 0   ...   so we have

6-3x > 0     Add 3x to both sides

6 > 3x        Divide both sides by 3

2 > x      which means the same thing as x < 2

So our domain is

(-∞, 2)

And that's it......
