The mapping diagram shows a function R(x).910111289Which mapping diagram shows the inverse of R(x)?O A.DOO VO6789INB.9101112AAA89c!1211→10989O D.9101112→ 8→ 7

Answer 1

Since we want to find the values of the inverse function, we have to change the values of x for y values.

x r(x)

6 9

7 10

8 11

9 12

Changing x for y we have.

r'(x) x

6 9

7 10
