Multiple Choice

Graph the Polar Equations of Conics
- $r = \frac { 2 } { 2 - 2 \cos \theta } \quad$ Identify the directrix and vertex.

• A) directrix: 1 unit(s) to the left of the pole at \(x = - 1\) vertex: \(\left( \frac { 1 } { 2 } , \pi \right)\)
• B) directrix: 1 unit(s) to the right of the pole at \(x = 1\) vertex: \(\left( \frac { 1 } { 2 } , 0 \right)\)
• C) directrix: 1 unit(s) above the pole at \(\mathrm { y } = 1\) vertex: \(\left( \frac { 1 } { 2 } , \frac { \pi } { 2 } \right)\)
• D) directrix: 1 unit(s) below the pole at \(\mathrm { y } = - 1\) vertex: \(\left( \frac { 1 } { 2 } , \frac { 3 \pi } { 2 } \right)\)
