Find the domain and range and describe the level curves for the function f(x,y). f (x, y) = \9 – x² – y² O Domain: all points in the xy-plain satisfying x² + y² <9. Range: all real numbers. Level Curves: circles with centers at (0,0) and radii r; 0 < r < 3. O Domain: all points in the xy-plain satisfying x² + y² < 9. Range: real numbers 0 < z < 3. Level Curves: circles with centers at (0,0) and radii r; 0 < r < 3. O Domain: all points in the xy-plain satisfying x + y = 9. Range: real numbers 0 < z < 3. Level Curves: circles with centers at (0,0) and radii r; 0 < r < 3. O Domain: all points in the xy-plain satisfying Range: real numbers 0 < z 3. Level Curves: circles with centers at (0,0) and radii r; 0 < r< 3.
