Question 215943
The limit is ZERO since the degree of the denominator is larger than the degree of the numerator!  If you divide numerator and denominator by x, you get 


{{{(2 -1/x)/(x+3+1/x) }}}


As x approaches infinity, you have a  numerator of 2 and a denominator of infinity.  The limit of 2 divided by an infinitely large denominator is 0.
