The video tutorial introduces non-linear functions, contrasting them with linear functions. It explains how to identify linear, quadratic, and cubic functions using tables and common differences. The tutorial covers graphing these functions, focusing on domain and range. It concludes with a practical application of cubic functions to determine the number of blocks in a cube, emphasizing the importance of recognizing patterns in mathematical functions.

What is a characteristic of a linear function's graph?

• It is a horizontal line.

• It is a curve.

• It has a constant rate of change.

• It is a vertical line.

How do you determine the rule for a linear function from a table of values?

• By identifying a common ratio.

• By finding a common difference.

• By squaring the values.

• By finding the sum of the values.

What pattern is observed in a quadratic function's table of values?

• A common fourth difference.

• A common third difference.

• A common first difference.

• A common second difference.

What is the rule for a quadratic function derived from the table of values?

• y = x^3

• y = 2x

• y = x + 2

• y = x^2

How is the rule for a cubic function determined from a table of values?

• By finding a common second difference.

• By finding a common third difference.

• By finding a common fourth difference.

• By finding a common first difference.

What is the rule for a cubic function derived from the table of values?

• y = x + 3

• y = x^3

• y = x^2

• y = 2x

What is the domain of the cubic function when applied to the cube problem?

• 0 to positive infinity

• All real numbers

• 1, 2, 3, 4, 5

• Negative infinity to positive infinity

What is the range of the cubic function when applied to the cube problem?

• 0 to positive infinity

• Negative infinity to positive infinity

• 1, 8, 27, 64, 125

• All real numbers

Why is a discrete graph used for the cube problem?

• Because the function is continuous.

• Because only whole blocks are used.

• Because the function is linear.

• Because the function is quadratic.

What is the relationship between the number of blocks per edge and the total number of blocks in a cube?

• The total number of blocks is half the blocks per edge.

• The total number of blocks is the square of the blocks per edge.

• The total number of blocks is the cube of the blocks per edge.

• The total number of blocks is twice the blocks per edge.
