Here is the correct way to fill in the blanks to describe functions:
• A function is a rule that relates I inputs to F variables.
An input is also called a(n) B x-value.
• An output is also called a(n) D y-value.
In a function, each input is paired with E exactly one output.
Therefore, the completed sentences are:
- A function is a rule that relates inputs to variables.
- An input is also called a(n) x-value.
- An output is also called a(n) y-value.
- In a function, each input is paired with exactly one output.
