Multiple Choice

A point is moving along the graph of the function $y = \frac { 1 } { 8 x ^ { 2 } + 3 }$ such that $\frac { d x } { d t } = 5$ centimeters per second. Find dy/dt when $x = 1$ .

A) $\frac { d y } { d t } = - \frac { 16 } { 121 }$
B) $\frac { d y } { d t } = - \frac { 80 } { 121 }$
C) $\frac { d y } { d t } = \frac { 80 } { 121 }$
D) $\frac { d y } { d t } = \frac { 16 } { 121 }$
E) $\frac { d y } { d t } = - \frac { 80 } { 11 }$
