find a&b if lim_(x rarr oo)((x^(2)+1)/(x+1)-ax-b)=0

If lim_(x rarr oo)((x^(2)+x+1)/(x+1)-ax-b)=4 then a=?b=?

If a (A) x=0 (B) x=1 (C) x=2 (D) None of these.

If lim_(x rarr oo){(x^(2)+1)/(x+1)-(ax+b)}=0, then find the value of a and b.

If x+2 is a factor of x^2+a x+2b and a+b=4 , then (a) a=1, b=3 (b) a=3, b=1 (c) a=-1, b=5 (d) a=5, b=-1

Let f(x)={(1/(|x|), for |x| ge 1),(ax^2+b,for |x| < 1)) . If f(x) is continuous and differentiable at any point, then (A) a=1/2, b=-3/2 (B) a=-1/2, b=3/2 (C) a=1,b=-1 (D) none of these

lim_(x rarr oo)((x^(2)+2x-1)/(2x^(2)-3x-2))^((2x+1)/(2x-1)) is equal to (a) 0 (b) oo(c)(1)/(2) (d) none of these
