Multiple Choice

Graph the Polar Equations of Conics
- $\mathrm { r } = \frac { 4 } { 1 + 2 \cos \theta } \quad$ Identify the directrix and vertices.

• A) directrix: 2 unit(s) to the right of the pole at \(x = - 2\) vertices: \(( - 4 , \pi ) , \left( \frac { 4 } { 3 } , 0 \right)\)
• B) directrix: 2 unit(s) to the left of the pole at \(x = 2\) vertices: \(( 4 , \pi ) , \left( - \frac { 4 } { 3 } , 0 \right)\)
• C) directrix: 2 unit(s) above the pole at \(\mathrm { y } = 2\) vertices: \(\left( \frac { 4 } { 3 } , \frac { \pi } { 2 } \right) , \left( 4 , \frac { \pi } { 2 } \right)\)
• D) directrix: 2 unit(s) below the pole at \(\mathrm { y } = - 2\) vertices: \(\left( - \frac { 4 } { 3 } , \frac { \pi } { 2 } \right) , \left( - 4 , \frac { \pi } { 2 } \right)\)
