Question 1178720
<pre>
Mary says that the graph of     3x^2 + 5x + 9
                            y = ---------------- 
                                 x^2 + 2x - 7
 
 will approach y = 1  as the x-values approach both positive and negative infinity. Is Mary correct?

No.  Think about it.  The lead terms of both numerator and denominator become increasingly important for x going either extreme to the right or to the left...
