Match the following curves in column I, with the areas bounded by the curve and x - axis

a. [x]2=[y]2, where 1≤x≤4⇒[x]=±[y]b.[|x|]+[|y|]=2 The graph is symmetrical about both x-axis and y-axis.  For x,y>0;[x]+[y]=2. ⇒[x]=0 and [y]=2,[x]=1 and [y]=1 or [x]=2 and [y]=0c.[|x|][|y|]=2 The graph is symmetrical about both x-axis and y-axis.  For x,y>0;[x][y]=2⇒[x]=1 and [y]=2 or [x]=2 and [y]=1 d. [|x|][|y|]=2, where −5≤x≤5.  The graph is symmetrical about both the axes.  For x,y>0,[x]=2[y],[y]≠0⇒[x]=2 and [y]=1 or [x]=4 and [y]=2
