This video tutorial by Stan Lyle covers the representation of functions using tables and graphs. It explains the concept of functions, input-output tables, and the difference between dependent and independent variables. The lesson includes examples of creating functions, input-output tables, and graphing functions. Practice problems are provided to reinforce learning, and additional resources are suggested for further practice.

What should you do when you encounter a 'you try it' slide during the lesson?

• Wait for the answer to be shown.

• Pause the video and attempt the problem.

• Skip to the next section.

• Rewind the video to review the content.

Which of the following is NOT an objective of this lesson?

• Learning how to solve quadratic equations.

• Understanding what a function is.

• Knowing the difference between dependent and independent variables.

• Learning how to graph a function.

What is a function in mathematical terms?

• A table with only one column.

• A graph with no variables.

• An operation that maps inputs to outputs.

• A set of random numbers.

In the function y = 5x + 1, what does the '5' represent?

• The output value.

• The independent variable.

• The constant term.

• The coefficient of x.

How can a function be compared to a machine?

• It breaks down inputs into smaller parts.

• It processes inputs to produce outputs.

• It duplicates inputs.

• It stores inputs for later use.

What is the purpose of an input-output table?

• To solve equations without variables.

• To graph equations directly.

• To list all possible functions.

• To show the relationship between inputs and outputs.

In the taxi fare example, what does the '1' in the function y = 5x + 1 represent?

• The cost per mile.

• The total fare.

• The base fare.

• The number of miles.

Why are negative x values not included in the taxi fare input-output table?

• The taxi cannot travel backwards.

• Negative values are not allowed in functions.

• They are not part of the domain.

• They would result in negative fares.

What is the domain in a function?

• The output of the function.

• The range of the function.

• The set of all possible x values.

• The set of all possible y values.

What is the range in a function?

• The set of all possible y values.

• The input of the function.

• The domain of the function.

• The set of all possible x values.
