The graph of r = -3 + 5cosθ is symmetric about the option (B) x axis only
In mathematics, symmetry has a more precise definition, and is usually used to refer to an object that is invariant under some transformations; including translation, reflection, rotation or scaling.
A graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense related.
Here,
The graph of r = -3 + 5cosθ is symmetric about the x axis only
Also when we plot the graph we can say that it is symmetric about x axis only.
Hence, the graph of r = -3 + 5cosθ is symmetric about the option (B) x axis only
