Find the Taylor series for f(x) centered at the given value of a. [Assume that f has a power series expansion. Do not show that Rn(x) → 0.] f(x) = 2/x , a = −3
Why have you put as the denominator? A polynomial does not have algebraic terms in denominators...
I suggest you reread what I posted above. You need to evaluate a number of derivatives at the point and substitute these and into the Taylor series formula.
