let fxx2x1 carefully sketch the graph yfx make sure to show
let f(x)=(x+2)/(x-1) carefully sketch the graph y=f(x) make sure to show your work and label coordinates of all intercepts and then explicit equations of all the asymptotes
Solution
f(x)=(x+2)/(x-1)
x intercept is
x+2=0
x=-2
(-2,0)
y intercept is
f(0)=2/-1=-2
(0,-2)
Vertical asymptote
x-1=0
x=1
Horizontal asymptote
Numerator and denominator have same degree, therefore horizontal asymptote is y= numerator\'s leading coefficient/denominator\'s leading coefficient
y=1/1=1
