$y=\mathrm{f}\left( x \right)$ $y=\frac{1}{\mathrm{f}\left( x \right)}$ \(y=\mathrm{f}'\left( x

Question

$y=\mathrm{f}\left( x \right)$ $y=\frac{1}{\mathrm{f}\left( x \right)}$ $y=\mathrm{f}'\left( x \right)$

Accepted Answer

For $y=\dfrac1{f(x)}$: maximum $(0,1)$, horizontal asymptote $y=0$. For $y=f'(x)$: zero $(0,0)$, horizontal asymptotes $y=-1$ and $y=1$, negative for $x0$.
