All non-negative real numbers c. Choose the correct description(s) of the level curves of f(x,y) = 8xy. Select all that apply. A. Hyperbolas, when f(x,y) # 0 B. The x- and y-axes, when f(x,y) = 0 C. Circles, when f(x,y) # 0 D. Straight lines, when f(x,y) # 0 d. Does the function's domain have a boundary? Select the correct choice and if necessary, fill in the answer box below to complete your choice. O A. Yes, at (Type an ordered pair. Use a comma to separate answers as needed.) O B. Yes, at =0 (Type an expression using x and y as the variables.) O C. Noe. Choose the correct description of the domain of f(x,y) = 8xy. O Closed region Open region O Both open and closed O Neither open nor closed f. Is the domain of f(x,y) = 8xy bounded or unbounded? O Unbounded O Bounded
