Find the Extreme Values of the Function and Where They $$y = \frac { \ln x } { x ^ { 2 } }$$

Multiple Choice

Find the extreme values of the function and where they occur.
- $$y = \frac { \ln x } { x ^ { 2 } }$$

A) Maximum value is $\frac { 1 } { 2 \mathrm { e } }$ at $\mathrm { x } = \mathrm { e } ^ { 1 / 2 }$ ; minimum value is 0 at $\mathrm { x } = 1$ .
B) Minimum value is $\frac { 1 } { 2 \mathrm { e } }$ at $\mathrm { x } = \mathrm { e } ^ { 1 / 2 }$ ; no maximum value.
C) Maximum value is $\frac { 1 } { 2 \mathrm { e } }$ at $\mathrm { x } = \mathrm { e } ^ { 1 / 2 }$ ; no minimum value.
D) None
