Question

Is the relation {(2, -1), (3, -1), (4, 7), (3, 5)} a function?

Answer 1

Yes

Explanation:

How do you determine if a relation is a function or not?

Identify the input values. Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.
