Help Please? Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 4 - 4 cos θ

Think about what the graph of 4cos(x) looks like by itself (since we are relating theta and r in the same manner as x and y, I will use x and y). Can you tell me (or draw for me) what it looks like?
