Tell if the function is symmetric with respect to the x-axis, y-axis, and origin.
3. 8x^2 - 2y^2 = 12
==> I got that it was symmetric to both the x- and y-axes. Is this right?
4. 5x^2 - 3y^2 = 18
==> I can't get anywhere with this equation -- I'm getting the answer that this equation is imaginary.
Can someone please show me how to do these? Thanks soooo much :D
