Answer: The graph of rectangular hyperbola represents the function f(x)=4/x.
Explanation: given function, f(x)= 4/x.
The above function shows equation of rectangular hyperbola or equilateral hyberbola.(because, it is the type of .)
Thus, the asymptote of the given function must be perpendicular.
Moreover, if x=2, y=2, if x=-2, y=-2
If x=4, y=1, if x=-4, y=-1
Therefore, this hyperbola is passing through points (2,2), (-2,-2), (4,1) and (-4,-1).
