`f(x)=(3x^2+a x+a+1)/(x^2+x-2)` and `lim_(x->-2)f(x)` exists. Then the value of `(a-4)` is__________

f(x)=(3x^(2)+ax+a+1)/(x^(2)+x-2) and lim_(x rarr-2)f(x) exists.Then the value of (a-4) is

If f(x) = (x^(2)-9)/(x-3) , find it Lim_(x to 3) f(x) exists .

f(x)={(ax+2, x 1):} , If lim_(x rarr1)f(x) exist then value of a is :

If f(x)=lim_(nrarroo) ((x^(2)+ax+1)+x^(2n)(2x^(2)+x+b))/(1+x^(2n)) and lim_(xrarrpm1) f(x) exists, then The value of a is

If f(x)=lim_(n->oo)((x^2+a x+1)+x^(2n)(2x^2+x+b))/(1+x^(2n))and lim_(x->+-1)f(x) exist, then The value of b is (a)-1 (b). 1 ( c.) 0 (d).2

If f(x)=lim_(n->oo)((x^2+a x+1)+x^(2n)(2x^2+x+b))/(1+x^(2n))and lim_(x->+-1)f(x) exist, then The value of b is (a) -1 (b). 1 ( c.) 0 (d). 2

If f(x)=lim_(nrarroo)((x^(2)+ax+1)+x^(2n)(2x^(2)+x+b))/(1+x^(2n)) and lim_(xrarrpm1)f(x) exists, then The value of b is

Let f(x)={{:(4x-5",",xle2),(x-a",",xgt2.):} If lim_(xrarr2)f(x) exists then find the value of a.
