r = 2 + 3 sin θ

Question

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. 

r = 2 + 3 sin θ

welshfella · Answer

this should help you find the answer
sin x is symmetrical about the origin
The 3  will stretch the graph of sinx  parallel to the y axis , factor 3
the + 2 will translate the graph 2 units upwards

Hmmm okay

I'm not sure what you mean

https://www.desmos.com/calculator/mkfyoh8dax there are the 3 graphs demonstrating the transformation of sin x to 2 + 3 sin x

welshfella · Answer

The green one is the final graph  y = 2 + 3 sin x.

haldko · Answer

Does that mean that it is symmetric about the x-axis?

If the x axis is a mirror,   is the green graph below the x axis the same as the part of green graph above the x axis?
