SOLUTION: Mary says that the graph of 3x^2 + 5x + 9 y = ----------- ---- x^2 + 2x

SOLUTION: Mary says that the graph of 3x^2 + 5x + 9 y = ----------- ---- x^2 + 2x - 7 will approach y = 1 as the x-

Question 1178720: 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?
