Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 2 cos 3θ
1 answer:
Take a quick peek at
brainly.com/question/10417591that's how you test for the y-axis, x-axis and origin
recall your symmetry identities, cos(- θ) = cos(θ)
so, simply replace θ for those values, and if the resultant function looks exactly like the original, then it has that symmetry.

Answer:
y intercept = (0,-1.2)
x intercept = (3.6,0)
Step-by-step explanation:
For y-int, x=0
3(0)-9(y)=10.8
9y=-10.8
y= -1.2
For x-int, y =0
3x - 9(0)=10.8
3x=10.8
x=3.6
