Question

Locate the critical points of f(x)=3x−4−x−3f\left(x\right)=$$3x^{-4}$-x^{-3}$$, and use the Second Derivative Test to identify whether these points are local maxima or minima.

Accepted Answer

fmin(4)=−1256f_{	ext{min}}\left(4ight)=-\frac{1}{256}

Answer

fmax(4)=−1256f_{	ext{max}}\left(4ight)=-\frac{1}{256}

Answer

fmin(−4)=7256f_{	ext{min}}\left(-4ight)=\frac{7}{256}

Answer

fmax(−4)=7256f_{	ext{max}}\left(-4ight)=\frac{7}{256}

Locate the critical points of f(x)=3x−4−x−3f\(\left\)(x\(\right\))=3x^{-4}-x^{-3}, and use the Second Derivative Test to identify whether these points are local maxima or minima.

Locate the critical points of $f (x) = 3 x^{- 4} - x^{- 3}$ , and use the Second Derivative Test to identify whether these points are local maxima or minima.
