Webb28 jan. 2024 · Sketch the level curves of f(x, y) = x2 + 4y2 − 2x + 2. Solution Fix any real number C. Then, for the specified function f, the level curve f(x, y) = C is the set of points (x, y) that obey x2 + 4y2 − 2x + 2 = C x2 − 2x + 1 + 4y2 + 1 = C (x − 1)2 + 4y2 = C − 1 Now (x − 1)2 + 4y2 is the sum of two squares, and so is always at least zero. Webb16 nov. 2024 · The domain of functions of two variables, z = f (x,y) z = f ( x, y), are regions from two dimensional space and consist of all the coordinate pairs, (x,y) ( x, y), that we could plug into the function and get back a real number. Example 1 Determine the domain of each of the following. f (x,y) =√x+y f ( x, y) = x + y boomer insurance group reviews
