Multiple Choice

Find the extreme values of the function and where they occur.
- $$y = \frac { x + 1 } { x ^ { 2 } + 2 x + 2 }$$

A) The maximum is $- \frac { 1 } { 2 }$ at $x = 0$ ; the minimum is $\frac { 1 } { 2 }$ at $x = - 2$ .
B) None
C) The maximum is 2 at $x = 0$ ; the minimum is $\frac { 1 } { 2 }$ at $x = - 2$ .
D) The maximum is $\frac { 1 } { 2 }$ at $x = 0$ ; the minimum is $- \frac { 1 } { 2 }$ at $x = - 2$ .
