Answer with explanation:

The given function is:

⇒ y =3 x

And it's inverse function can be Calculated by, replacing , x by y, and , y by x, in the above equation

⇒x=3 y, is the equation of inverse function.

Both the original function , and inverse function passes through origin, As well as Origin is the point of Intersection, which can be shown as follows:

3 x-y=0-----(1)

x-3 y=0

3 x - 9 y =0 ------(2)

EQ.(1) - Eq.(2)

3 x - y - (3 x- 9 y)=0

-y + 9 y=0

8 y=0

y=0

Putting the value of , y in equation (2)

x=3 × 0

x=0

Point of intersection of ,f(x) and it's inverse =(0,0)
