Explanation Given information: f ( x ) = x 3 − 6 x 2 − 15 x + 20 Calculation: f ( x ) = x 3 − 6 x 2 − 15 x + 20 Differentiating with respect to ‘x’, we get f ' ( x ) = d d x ( x 3 − 6 x 2 − 15 x + 20 ) = d d x ( x 3 ) − d d x ( 6 x 2 ) − d d x ( 15 x ) + d d x ( 20 ) = d d x ( x 3 ) − 6 d d x ( x 2 ) − 15 d d x ( x ) + d d x ( 20 ) = ( 3 x 2 ) − 6 ( 2 x ) − 15 ( 1 ) + 0 = 3 x 2 − 12 x − 15 ⇒ f ' ( x ) = 3 x 2 − 12 x − 15 Put f
