Consider the Taylor polynomial Tn(x) centered at x=22 for all n for the function f(x)=1x−1, where i is the index of summation. Find the ith term of Tn(x). (Express numbers in exact form. Use symbolic notation and fractions where needed. For alternating series, include a factor of the form (−1)n in your answer.)

Ascientist wants to use a model to present the results of his detailed scientific investigation. why would a model be useful? a )because the model makes the concepts easier to understand b) because the model is easy to put together and to use c) because the model prevents other scientists from asking questions d) because the model requires the audience to pay full attention to it i don't know what to choose because between a and d a is much more likely than d because it only wants to get the attention of the audience. i'm confuse.
