Найдем производную f при х = - 2, функция равна f ( х ) = ( 5 + 2 * х ) ^ 4 .Производная f ( х ) = ( ( 5 + 2 * х ) ^ 4 ) \' = 4 * ( 5 + 2 * x ) ^ ( 4 - 1 ) * ( 5 + 2 *x ) \' = 4 * ( 5 + 2 * x ) ^ 3 * ( 5 + 2 * x ) \' = 4 * ( 5 + 2 * x ) ^ 3 * ( 5 \' + 2 * x \' ) = 4 * ( 5 + 2 * x ) ^ 3 * ( 0 + 2 * 1 ) = 4 * ( 5 + 2 * x ) * 2 = 8 * ( 5 + 2 * x ) ;Производная f ( - 2 ) = 8 * ( 5 + 2 * ( - 2 ) ) = 8 * ( 5 - 2 * 2 ) = 8 * ( 5 - 4 ) = 8 * 1 = 8 ; Ответ: Производная f ( - 2 ) = 8.
