question 4

Multiple Choice

Find the derivative of the function. $u ( x ) = \cos \left( x ^ { 2 } - 2 x \right)$

• A) \(u ^ { \prime } ( x ) = ( 2 x - 2 ) \cos \left( x ^ { 2 } - 2 x \right)\)
• B) \(u ^ { \prime } ( x ) = - ( 2 x + 2 ) \sin \left( x ^ { 2 } - 2 x \right)\)
• C) \(u ^ { \prime } ( x ) = - ( 2 x - 2 ) \cos \left( x ^ { 2 } - 2 x \right)\)
• D) \(u ^ { \prime } ( x ) = - ( 2 x - 2 ) \sin \left( x ^ { 2 } - 2 x \right)\)
• E) \(u ^ { \prime } ( x ) = ( 2 x + 2 ) \sin \left( x ^ { 2 } - 2 x \right)\)
