Explanation Given information: The function is f ( x ) = x 3 + 3 x − 1 and the point at x = − 1 . Explanation: The n th Taylor polynomial of f ( x ) at x = a is the polynomial p n ( x ) defined by p n ( x ) = f ( a ) + f ' ( a ) 1 ! ( x − a ) + f " ( a ) 2 ! ( x − a ) 2 + ........ + f n ( a ) n ! ( x − a ) n … (1) As f ( x ) = x 3 + 3 x − 1 , f ' ( x ) = 3 x 2 + 3 f " ( x ) = 6 x f ' ' ' ( x ) = 6 f 4 ( x ) = 0 Therefore, at x = − 1 , the values of f ( x ) and its derivatives are f ( − 1 ) = ( − 1 ) 3 + 3 × ( − 1 ) − 1 = − 1 − 3 − 1 = − 5 f ' ( − 1 ) = 3 × ( − 1 ) 2 + 3 = 3 + 3 = 6 f " ( − 1 ) = 6 × ( − 1 ) = − 6 f ' ' ' ( − 1 ) = 6 f 4 ( − 1 ) = 0 For the third Taylor polynomial, n = 3 , so substitute this value in the equation (1). So, the third Taylor polynomial is, p 3 ( x ) = f ( a ) + f ' ( a ) 1 ! ( x − a ) + f " ( a ) 2 ! ( x − a ) 2 + f ' ' ' ( a ) 3 ! ( x − a ) 3 Therefore, at x = − 1 p 3 ( x ) = f ( − 1 ) + f ' ( − 1 ) 1 ! ( x + 1 ) + f " ( − 1 ) 2 ! ( x + 1 ) 2 + f ' ' ' ( − 1 ) 3 ! ( x + 1 ) 3 Substitute the values of f ( − 1 ) , f ' ( − 1 ) , f ' ' ( − 1 ) , f ' ' ' ( − 1 ) in above equation, ⇒ p 3 ( x ) = − 5 + 6 1 ! ( x + 1 ) + − 6 2 ! ( x + 1 ) 2 + 6 3 ! ( x + 1 ) 3 ⇒ p 3 ( x ) = − 5 + 6 ( x + 1 ) − 6 2 ( x + 1 ) 2 + 6 6 ( x + 1 ) 3 ⇒ p 3 ( x ) = − 5 + 6 ( x + 1 ) − 3 ( x + 1 ) 2 + ( x + 1 ) 3
