5-79.

Sometimes people make mistakes when differentiating using the Chain Rule. Explain the mistakes in the work below. Then write the correct derivatives. Homework Help ✎

*f*(^{ }*x*) = –5(6*x*^{4}– 1)^{10}+*π*

*f*′(*x*) = –50(24*x*^{3}– 1)^{9}*f*(^{ }*x*) = sin(*x*^{2}–*x*)

*f*′(*x*) = − cos(*x*^{2}−*x*)
