= = =
The denominator becomes,
( + 3)(3 − 1)( + 1)
The original rational function becomes,
(2 − 1)( + 3)( − 2)(2 + 1)
( ) =
( + 3)(3 − 1)( + 1)
This simplifies to,
(2 − 1)( − 2)(2 + 1)
( ) =
(3 − 1)( + 1)
In the plot of the function observe the asymptotes,
what is the gradient and intercept of the oblique
asymptote?
