1.`f(x)=1/x`

It is rectangular hyperbola with centre at (0,0). The area enclosed by curve and axes is 1 sq unit.

a. `y=-1/x`

As x approaches infinite , y approaches to 0 and as x aproaches to 0, y approaches to negative infinite. It is graph of rectangular hyperbola. The area enclosed between curve and axes is 1 sq. unit.Its centre at (0,0).

b. `y=2/x`

As x approaches infinite , y approaches to 0 and as x aproaches to 0, y approaches to infinite. It is graph of rectangular hyperbola. The area enclosed between curve and axes is 2 sq. unit. Its centre at (0,0).

c. `y=1/x-3`

As x approaches infinite , y approaches to -3 and as x aproaches to 0, y approaches to infinite. It is graph of rectangular hyperbola. Centre shifted to (0,-3) .

d.`y=1/x+1`

As x approaches infinite , y approaches to 1 and as x aproaches to 0, y approaches to infinite. It is graph of rectangular hyperbola. Centre shifted to (0,1) .
