To help you fill in the blanks for the assessment, here are the correct answers:

1. The variable that represents the input of a function is called the independent variable.
2. The variable that represents the output of a function is called the dependent variable.
3. When we use the notation f(x), we are using function notation.
4. The function f refers to the domain, the range, and the rule that takes elements in the domain and outputs elements in the range.

If you'd like more detailed explanations for these answers, feel free to ask! Here are some related questions that could expand your understanding:

1. What is the difference between a dependent and independent variable in the context of a function?
2. Can a function have more than one independent variable?
3. How do you determine the domain of a given function?
4. Why is function notation important in mathematics?
5. What is the difference between a function's domain and its range?

Tip: A function's domain is the set of all possible input values (independent variable), while its range is the set of all possible output values (dependent variable).
