Exercise 11 Page 267

Exchange the x- and y-coordinates in each ordered pair.

{ (7.4,- 3), (4,- 1), (0.6,1), (- 2.8,3), (- 6.2,5)}

Practice makes perfect

We can interpret the given table as a set of ordered pairs.

x	y	Ordered Pair
-3	7.4	(-3,7.4)
-1	4	(-1,4)
1	0.6	(1,0.6)
3	-2.8	(3,-2.8)
5	-6.2	(5,-6.2)

To find the inverse of a relation written as a table, we exchange the x- and y-coordinates of each ordered pair.

Given Point	Inverse Point
( -3, 7.4)	( 7.4, -3)
( -1, 4)	( 4, -1)
( 1, 0.6)	( 0.6, 1)
( 3, -2.8)	( -2.8, 3)
( 5, -6.2)	( -6.2, 5)

Let's write the inverse relation as a data set. { (7.4,- 3), (4,- 1), (0.6,1), (- 2.8,3), (- 6.2,5)}
