ARE the correct answers! I recently took this the other day and got a 5/5. Ignore the other comments trying to mislead everyone..
Thanks^^ 100% right
1. Graph x^2 + y^2 = 9. What are its lines of symmetry? Ans: A (Every line through the center is a line of symmetry).
2.Graph x^2 + 9y^2 = 25. What are the domain and range?
Ans: C
Domain: –5 ≤ x ≤ 5
Range: –1.67 ≤ y ≤ 1.67
3. Graph x2 – y2 = 16. What are its lines of symmetry?
Ans: D (It has two lines of symmetry, the x-axis and the y-axis).
4. Identify the center and intercepts of the conic section. Then find the domain and range.
Ans: B. The center of the ellipse is (0, 0).
The x-intercepts are (–3, 0) and (3, 0).
The y-intercepts are (0, 5) and (0, –5).
The domain is {x | –3 ≤ x ≤ 3}.
The range is {y { –5 ≤ y ≤ 5}.
5. Identify the center and intercepts of the conic section. Then find the domain and range.
Ans: C. The center of the hyperbola is (0, 0).
The y-intercepts are (0, 5) and (0, –5).
The domain is all real numbers.
The range is {y | y ≤ –5 or y ≥ 5}.

Becareful they switched it up
Noted. Thank you for confirming!
Can someone post the questions with the answers because sometimes they replace the options?

on the tests/quizzes that you take INSIDE the lesson slide they can’t switch the answers, I took the unit test and these are the correct answers for it so u will 2!
#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
