I need help solving the two problems below. Thanks

Question

For each equation, determine whether its graph is symmetric with respect to the -axis, the -axis, and the origin.

Check all symmetries that apply.

1. y=-sqrt(4-x^(2))

2. 34x^(2)+12y^(2)=18

Answer 1

1.With each point (x,y) we also have point
(-x,y)-->the graph is symmetric y-axis

2.With each point (x,y) we have points
(-x,y), (x,-y), (-x,-y) -->
y-axis, x-axis, origin

Answer 2

Thanks!!!!
