(1, - 2)

$(1, - 2)$ ,

(3, 6)

$(3, 6)$

Step 1

Since there is one value of

y

$y$ for every value of

x

$x$ in

(1, - 2), (3, 6)

$(1, - 2), (3, 6)$ , this relation is a function.

The relation is a function.

Step 2

Use the definition of the inverse of a function to find the inverse of the set. The inverse is found by swapping the values of

x

$x$ and

y

$y$ in each ordered pair.

(- 2, 1), (6, 3)

$(- 2, 1), (6, 3)$
