Answer

(a) Each second coordinate is paired with only one first coordinate. Thus, the given function is one-to-one. (b) The inverse can be found by interchanging the first and second coordinates. Thus, the inverse of the given function is: $$\left\{(2, 1) (5, 3), (8, 5), (10, 6)\right\}$$

Work Step by Step

Recall: A one-to-one function is a function where second coordinate is paired to only one first element. (a) Note that each second coordinate is paired with only one first coordinate. Thus, the given function is one-to-one. (b) The inverse can be found by interchanging the first and second coordinates. Thus, the inverse of the given function is: $$\left\{(2, 1) (5, 3), (8, 5), (10, 6)\right\}$$
