<PRE><B>Question 171170</B>
The graph of y = f(x) has one vertical asymptote, at x= -7 , and a horizontal asymptote at y = 21 . The graph of f crosses the x-axis once, at x = 6 , and the y-axis at y = -18 . Find the simplest possible formula for the rational function.
---------------------
y = (ax+b)/(cx+d) + e
----------
y = (21x-21*6)/(x+7) + 0
