You can
put this solution on YOUR website!I am assuming that you are asking about function
The domain is all points where the function is defined. It is defined in all points where the denominator 3x+1 is not 0. It is zero at the point x=-1/3, obviously.
So, the
domain is all X except -1/3.
The range is all points, which becomes obvious when you try to draw the graph. The function approaches plus and minus infinity around point x=-1/3, and also gets to zero in point x=-4/5.
