Trig

I need help solving the two problems below. Thanks

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

  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

    what would a graph look like if.. y= (3/4)x + 2 and the domain is... x = {-8,-4,0,4,8} would it be discrete or continous? Kelly you should be able to see that the first equation is a line. You should be able to determine the slope
