c
An output is a special type of relation for which there is a rule that pairs each input with exactly one output.

d
An output is a set of ordered pairs in which no y-value repeats.

Answer 1

• B is the best definition of output

Explanation:

a . An output is the value that determines another based on the relation or the function rule, usually the x-values in a set of ordered pairs or on a table or graph.

• Incorrect. Output is defined by input.

b . An output is the result of a relation or the function rule, usually the y-values in a set of ordered pairs or on a table or graph.

• Correct

c . An output is a special type of relation for which there is a rule that pairs each input with exactly one output.

• Incorrect. Output is the result of relation but not pairing rule.

d . An output is a set of ordered pairs in which no y-value repeats.

• Incorrect. y-values can repeat.
