Is the following relation a function?{(3, −2), (1, 2), (−1, −4), (−1, 2)}
Accepted Solution
A:
Answer:It's not a function.Step-by-step explanation:A function is a process or a relation that associates each element x of a set X, to a single element y of another set Y.We have:{(3, -2), (1, 2), (-1, -4), (-1, 2)}for x = -1 are two values of y = -4 and y = 2. Therefore this realtion is not a function.
