Question

Which of the following functions is the inverse of the function {(1,2),(3,4),(6,8)} A.{(6,8),(3,4),(1,2) B.{(2,1),(4,3),(1,2)} C.{(2,1),(4,3),(8,6)D{(2,1),(3,4),(8,6)}

Answer 1

C. that was so easy yo

Answer 2

C. {(2,1),(4,3),(8,6)

Explanation:

To find the inverse function, the values of "x" and "y" must be exchanged, that is, the values of each ordered pair must be exchanged.

Thus, option "C" complies with this procedure, as evidenced as follows:

Function {(1,2), (3,4), (6,8)}

Pair (1,2) the inverse is (2,1)

Pair (3,4) the inverse is (4,3)

Pair (6,8) the inverse is (8,6)

The inverse function is:

{(21), (4,3), (8,6)}
