Question

The table show points on the graph of f(x).

(img)

Select the point that is on the graph of the inverse function f-1(x).

Answer 1

Answer: Choice C. (9,6)

Step-by-step explanation:

The point (6,9) is on the graph of f(x) as shown in the second to last row of the table. Recall that the inverse function will have us swap the roles of x and y. So that means we go from (x,y) to (y,x). Therefore, if (6,9) is on f(x) then (9,6) is on the inverse.
