A) vertex: $\left( 0 , - \frac { 5 } { 4 } \right)$ focus: $$\left( 0 , - \frac { 1 } { 28 } \right)$$
B) vertex: $\left( 0 , \frac { 5 } { 4 } \right)$ focus: $$\left( - \frac { 1 } { 7 } , - \frac { 1 } { 7 } \right)$$
C) vertex: (0,0) focus: $\left( - \frac { 1 } { 28 } , 0 \right)$
D) vertex: (0,0) focus: $\left( - \frac { 1 } { 7 } , 0 \right)$
E) vertex: (0,0) focus: $\left( 0 , - \frac { 1 } { 7 } \right)$
