The graph of f(x) is shown below.
if f(x) and its inverse function, f^-1 (x), are both plotted on the same coordinate plane, where is their point of intersection?

(2,2)

Step-by-step 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)

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
