Question

Which of the following best defines a function?

Answer 1

Answer: A. A function is a special type of relation for which there is a rule that pairs each input with exactly one output.

Option B is incorrect because it does not include that there cannot be two x-values with the same y-value. Option C is incorrect because it is a relation, not just a set of ordered pairs. Option D is incorrect because there is a particular pattern in a function.

Hope this helps!
