Multiple Choice

Find the vertex, focus, directrix, and focal width of the parabola.
- $$x = 8 y ^ { 2 }$$

A) Vertex: $( 0,0 )$ ; Focus: $\left( \frac { 1 } { 32 } , 0 \right) ;$ Directrix: $x = \frac { 1 } { 32 } ;$ Focal width: 32
B) Vertex: $( 0,0 )$ ; Focus: $\left( \frac { 1 } { 8 } , 0 \right) ;$ Directrix: $x = - \frac { 1 } { 8 } ;$ Focal width: $0.13$
C) Vertex: $( 0,0 )$ ; Focus: $\left( 0 , \frac { 1 } { 32 } \right) ;$ Directrix: $y = - \frac { 1 } { 32 }$ ; Focal width: 32
D) Vertex: $( 0,0 )$ ; Focus: $\left( \frac { 1 } { 32 } , 0 \right) ;$ Directrix: $x = - \frac { 1 } { 32 } ;$ Focal width: $0.13$
