find the slant asymptote of the graph of the rational function and b. use the slant asymptote to graph the rational function
f(x)x^2+x-20/x-7
..
a. find the slant asymptote of the graph of f.

y=(x+8) is the equation of the slant asymptote
..
b. use the slant asymptote to graph the rational function. determine the symmetry of the graph of f.
See graph below:
Graph not symmetrical.
..
c. find the y-intercept(s)
set x=0
y=-20/-7=20/7
y-intercept:(0,(20/7))
..
d. find the x-intercept(s)
set y=0
x^2+x-20=0
(x+5)(x-4)=0
x-intercepts:(4,0) and (-5,0)
..
e. find the vertical asymptote. x=7
f. find the horizontal asymptote. y=(none)
..
