Algebra-1

To determine if the relation is a function, we need to ensure that each input (x) has exactly one corresponding output (y).

Now, check each input to see if it has exactly one output:

−5 maps to 91 (one output)

0 maps to 91 and 17 (two different outputs)

3 maps to 17 (one output)

7 maps to 4 (one output)

Since 0 has two different outputs (91 and 17), the relation does not satisfy the definition of a function. In a function, each input must have exactly one output.
