Question

Which of the following best defines an output? (4 points)

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.


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.


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


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

Answer 1

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 best disfines an output because an input can have multiple outputs like

x y

4 5

3 5

6 5

but a function cannot have the same input with different outputs like

this example shows what is not a function

x y

3 5

3 6

4 79

4 64

this is not a function

Explanation:

Answer 2

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.

Usually, output refers to the dependent value of a function rule.

It is also correct that the y coordinate of ordered pairs, graphed points, and in a function table.
