#1. Every line through the center is an axis of symmetry. The x- and y- axes are just two of them.
#2. Not sure what the scrambled symbols are, but
domain is -5 <= x <= 5
range is -5/3 <= y <= 5/3
#3. Since + came out ok, I assume the equation is
x^2 - y^2 = 16
As you say, x- and y-axes are the axes of symmetry
#4. If your choice is correct, the equation of the ellipse must have been
x^2/9 + y^2/25 = 1
#5. If your choice is correct, the equation of the hyperbola must have been
y^2/25 - x^2 = 1
