question 387

Multiple Choice

Select the graph of the polar equation using symmetry, zeros, maximum r-values, and any other additional points.
$r = 4 - 6 \cos \theta$

• A)Symmetric with respect to the polar axis \(| r | = 10\) when \(\theta = \pi\) \[r = 0 \text { when } \cos \theta = \frac { 4 } { 6 }\]
• B)Symmetric with respect to the polar axis \(| r | = 10\) when \(\theta = \pi\) \[r = 0 \text { when } \cos \theta = \frac { 4 } { 6 }\]
• C)Symmetric with respect to the polar axis \(\begin{array} { l } | r | = 10 \text { when } \theta = \pi \\ r = 0 \text { when } \cos \theta = \frac { 4 } { 6 } \end{array}\)
• D)Symmetric with respect to the polar axis \(| r | = 10\) when \(\theta = \pi\) \[r = 0 \text { when } \cos \theta = \frac { 4 } { 6 }\]
• E)Symmetric with respect to the polar axis \(| r | = 10\) when \(\theta = \pi\) \[r = 0 \text { when } \cos \theta = \frac { 4 } { 6 }\]
