Can someone check my answers on exploring conic sections?
1. Graph x2 + y2 = 9. What are its lines of symmetry?
Every line through the center is a line of symmetry.
The y-axis and the x-axis are lines of symmetry.( my choice)
Every line through the center is a line of symmetry.
The y-axis and the x-axis are lines of symmetry.
2. Graph x2 + 9y2 = 25. What are the domain and range?
Domain: 每3 ≒ x ≒ 3
Range: 每3 ≒ y ≒ 3
Domain: 每5 ≒ x ≒ 5
Range: 每5 ≒ y ≒ 5 (my choice)
Domain: 每5 ≒ x ≒ 5
Range: 每1.67 ≒ y ≒ 1.67
Domain: 每1.67 ≒ x ≒ 1.67
Range: 每5 ≒ y ≒ 5
3. Graph x2 每 y2 = 16. What are its lines of symmetry?
It has four lines of symmetry, the x-axis, the y-axis, y = x, and y = 每x.
Every line through the center is a line of symmetry.
It has four lines of symmetry, the x-axis, the y-axis, y = x, and y = 每x.
It has two lines of symmetry, the x-axis and the y-axis. ( my choice)
4. Identify the center and intercepts of the conic section. Then find the domain and range.
The center of the ellipse is (0, 0).
The x-intercepts are (0, 5) and (0, 每5).
The y-intercepts are (每3, 0) and (3, 0).
The domain is {x | 每3 ≒ x ≒ 3}.
The range is {y { 每5 ≒ y ≒ 5}.
The center of the ellipse is (0, 0).
The x-intercepts are (每3, 0) and (3, 0).
The y-intercepts are (0, 5) and (0, 每5).
The domain is {x | 每3 ≒ x ≒ 3}.
The range is {y { 每5 ≒ y ≒ 5}.( my choice)

The domain is {y { 每5 ≒ y ≒ 5}.
The range is {x | 每3 ≒ x ≒ 3}.
The center of the ellipse is (0, 0).
The x-intercepts are (0, 5) and (0, 每5).
The y-intercepts are (每3, 0) and (3, 0).
The domain is {y { 每5 ≒ y ≒ 5}.
The range is {x | 每3 ≒ x ≒ 3}.
5. Identify the center and intercepts of the conic section. Then find the domain and range.
The center of the hyberbola is (0, 0).
The y-intercepts are (0, 5) and (0, 每5).
The domain is all real numbers.
The range is {y | y ≡ 每5 or y ≒ 5}.
The center of the hyberbola is (0, 0).
The x-intercepts are (0, 5) and (0, 每5).
The domain is all real numbers.
The range is {y | y ≒ 每5 or y ≡ 5}.
The center of the hyberbola is (0, 0).
The y-intercepts are (0, 5) and (0, 每5).
The domain is all real numbers.
The range is {y | y ≒ 每5 or y ≡ 5}.(my choice)
The center of the hyberbola is (0, 0).
The x-intercepts are (0, 5) and (0, 每5).
The domain is all real numbers.
The range is {x | x ≒ 每5 or x ≡ 5}.

#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
