For the rational function sx1 x9 a Find the horizontal or sl
For the rational function s(x)-1 x-9 (a) Find the horizontal or slant asymptote, if any. (3 points) (b) Find the vertical asymptotes, if any. (3 points) (c) Find the x and y intercepts, if any. (3 points)
Solution
a. here numerator\'s and denominator\'s degrees are equal
Therefore horizontal asymptote,
y=numerator\'s leading coefficient /denominaor\'s leading coefficient
y=1/1=1
.b. Vertical asymptote
x2-9=0
x2=9
x=-3,3
c. x intercepts, f(x)=0
x2-1=0
x2=1
x=-1,1
(-1,0),(1,0)
