1 Find the Taylor series of f (x) = centered at c = 8. 1 x Choose the Taylor series. O 1 n+1 (x - 7)" 1- x 2 (D 8,.\" 1 _ n+1 (x 8)" 1 _ x _ 20( 1) 7n+1 O O 1 _=1(1)"("'8)n+1 O1 n=0 1 n 7n+l _ x:( 1) (x _ 8)" Identify the interval on which the expansion is valid. (Give your answer as an interval in the form (*, *)_ Use the symbol co for innity, U for combining intervals, and an appropriate II II[ II ['II]II type of parenthesis "(", "), depending on whether the interval is open or closed. Enter 6 if the interval is empty. Express numbers 1n exact form. Use symbolic notation and fractions where needed.) The expansion is valid for: 2
