Is the relation a function or not? If it is a function, determine if it is one-to-one, onto, both, or neither. Explain. { (2, 4); (4, -2); (1, 5); (0, 3) }

yes ; it's a function

Step-by-step explanation:

The relation given in the exercise is a function since each input element or domain has its only output element or range for example;

  2  → 4  ( 2  corresponds to only 4)

  4  → -2  ( 4 corresponds to only -2)

  1  → 5   ( 1 corresponds to only 5)

  0 → 3   ( 0 corresponds to only 3)
