Question

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin.

r = 9 sin 7θ

Answer 1

I believe it is the origin...

Answer 2

this isnt multiple choice so i need to explain the answer D;

Answer 3

You need to show your work and explain the answer in any case.

Answer 4

It's a sine, so it's likely symmetrical about the y axis and not the x-axis.
That 7 is odd, so there are 7 lobes. Can't be symmetrical about the origin with 7 lobes,

Get familiar with the graph types.
