Let f(x)={((x^3+2x^2-x-2)/(x^3-2x^2-x+2)...

Let `f(x)={((x^3+2x^2-x-2)/(x^3-2x^2-x+2), for |x| lt 1),(x^2+ax+b, for |x| ge 1):}` be continuous for all `x`. Now answer the question:The values of `a` and `b` are given by
`(A)` `a=-8/3,b=-4/3`
`(B)` `a=4/3,b=-8/3`
`(C)` `a=-4/3,b=-8/3`
`(D)` `a=-4/3,b=8/3`
