 3.6 Calculating Higher-Order Derivatives LEARNING OBJECTIVE FUN-3.F Determine higher order derivatives of a function FUN-3.F.1 Differentiating f  ′ produces the second derivative f  ″, provided the derivative of f  ′ exists; repeating this process produces higher order derivatives of f . FUN-3.F.2 Higher-order derivatives are represented with a variety of notations. For $y=f\left( x \right)$ ,notations for  the second derivative include $\frac{{{{d}^{2}}y}}{{d{{x}^{2}}}},{{f}'}'\left( x \right),$ , and ${{y}'}'$ . Higher-order derivatives can be denoted $\frac{{{{d}^{n}}y}}{{d{{x}^{n}}}}$ or ${{f}^{{\left( n \right)}}}\left( x \right)$
