Answer:
(2,2)
Explanation:
1. Find the equation of the function f(x). The graph of this function passes through the points (3,0) and (0,6). Then its equation is

2. Find the equation of the inverse function


Change x into y and y into x:

3. Find the point of intersection solving the system of two equations:

Equate right parts:

Hence, the point of intersection has coordinates (2,2)
