A) Vertex: $\left( - \frac { 7 } { 2 } , 1 \right)$ ;Focus: $\left( - \frac { 7 } { 2 } , 2 \right)$ ;Directrix: $y = 0$
B) Vertex: $\left( - \frac { 7 } { 2 } , 2 \right)$ ;Focus: $\left( - \frac { 7 } { 2 } , 2 \right)$ ;Directrix: $y = 1$
C) Vertex: $\left( - \frac { 7 } { 2 } , 2 \right)$ ;Focus: $\left( - \frac { 7 } { 2 } , 1 \right)$ ;Directrix: $y = 0$
D) Vertex: $\left( - \frac { 7 } { 2 } , 1 \right)$ ;Focus: $\left( - \frac { 7 } { 2 } , 2 \right)$ ;Directrix: $y = 1$
E) Vertex: $\left( - \frac { 7 } { 2 } , 1 \right)$ ;Focus: $\left( - \frac { 7 } { 2 } , 1 \right)$ ;Directrix: $y = 1$
