Find the domain of the following function. If possible, give a description of the domain in words (for example, all points outside a sphere of radius 1 centered at the origin). f(w,x.y,z) = 12-w= _x2 -y2 -zz Find the domain of the function. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. {(w,X,y,z): 2 2} O B. {(w,x,y,z): $ 2} O C. {(w,x,y,z): w#x, wzy, w#z, x#y, x#z, y#2) O D. {(w,x,y,z): #2} (Use a comma to separate answers as needed.) O E. R Give a description of the domain in words. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. All points not on the plane w = O B. All points on or above the plane z = O C. All points not on the planes w = x, w =y, w =z, x =y, x=z, and y =z O D. All points on the plane x = O E. All points on or below the plane y = OF. All points in R* O G. None of the above descriptions describe the domain in words.Evaluate the limit lim 2 2 (EJHU-U E E X 3" <:> l 1 13 _ys Find an expression that is equal to tiny) = 2, for all (m) in the domain off, that will be better suited to nd the limit it it exists.
