Sagot :
Hi there!

I believe your answer is:
D) {(1, 2), (2,4), (−1, 2), (0,3)}

Here’s why:
- A function is a relation in which one element of the domain is assigned to exactly one element of the range.
- This means that the domain (x) values must not repeat.
⸻⸻⸻⸻
Option A's answer is incorrect, as the domain value of '5' repeats.
{(5, 0), (0, 1), (5, 2), (4,4)}
⸻⸻⸻⸻
Option B is not a function due to the repeating '-4' value.
{(0, 1), (−4, 1), (4, 2), (−4,−1)}
⸻⸻⸻⸻
The '3' in option C's given relation repeats.
{(3, 2), (2,1), (−1, 2), (3,3)}
⸻⸻⸻⸻
Option D is the correct answer, as there are no domain values that repeat.
{(1, 2), (2,4), (−1, 2), (0,3)}
Therefore, option D is a function.
⸻⸻⸻⸻
