This question is most certainly asking about domain!The minimum value of f (x, y) = x 2 y 2 f (x, y) = x 2 y 2 is zero (attained when x = y = 0) x = y = 0) When x = 0, x = 0, the function becomes z = y 2, z = y 2, and when y = 0, y = 0, then the function becomes z = x 2 z = x 2 These are crosssections of the graph, and are parabolas Recall from Introduction to Vectors in Space thatSo f(x;y) is defined only if x2 y2 0 In other words, the domain is x2 y2 0 Note that x2 y2 = (x y)(x y) = 0 Therefore the boundary is the union of two diagonal lines passing through the origin The domain does contain the boundaries Sketch the graph of f(x;y) = e y Because the function f(x;y) does not depends on x, the section of

The domain of y=f(x) is the range of values of x such that f(x) exists We know that the ln() function does not admit negative arguments, so the domain of f(x) consist of the ranges of x which makes x^24x nonnegative, orDomain= f(x;y) 2R2 x y2 >0g = f(x;y) 2R2 x>y2g While it wasn't necessary to sketch the domain in the xyplane, here is a diagram showing the region Note, the domain is shaded in blue, with an open (dashed) boundary, since ln is unde ned for zero For the range, note that when y= 0, we have f(x;0) = ln(x), and since (x;0) is in our domainThe domain is rather straightforward since all you need is the expression within the root sign to be nonnegative That is, you need 1 x − y2 ≥ 0 or in more simple terms 1 x ≥ y2 So Dom (f(x, y)) = {1 x ≥ y2 ∣ x, y ∈ R} The range is slightly more tricky but not so much
