\lim \limits_{{x \rightarrow \infty}}\left\{\frac{x^2+1}{x+1}-a x-b\right\}=2

, then

View answer and explanation

Correct option: D

a=1, b=-3

Option D (

a=1, b=-3

) is correct because for the limit to be 2, the coefficients of

x^2

must be 0 and the ratio of the coefficients of

x

must be 2.
