\lim \limits_{{x \rightarrow \infty}}\left(\frac{x^2+x+1}{x+1}-a x-b\right)=4

, then

View answer and explanation

Correct option: B

a=1, b=-4

Option B (

a=1, b=-4

) is correct because for the limit to be 4, the coefficients of

x^2

must be 0 and the ratio of the coefficients of

x

must be 4.
