Determine the asymptotes and use to graph: F(x) = (x^2 + x) / (x - 1)
**
When degree of numerator is one degree higher than that of the denominator, you have slant asymptotes. To find equation of slant asymptote, divide numerator by denominator.
By long division you will get a quotient: (x+2)+R=2/(x+1).
Equation of the asymptote: y=x+2
Vertical asymptotes:
set denominator=0, then solve for x
x-1=0
x=1
vertical asymptote: x=1
number line:
F(x) = (x^2 + x) / (x - 1)
F(x)=x(x+1)/(x-1)
<...-...-1....+....0...-....1...+..>
