Multiplication Signs and Graph Behavior

The video tutorial focuses on understanding the role of signs in multiplication and their impact on graphing. It explains how multiplying positive and negative numbers affects the result and introduces patterns in multiplication. The tutorial also covers graphing factors, using factor lines, and analyzing graph regions based on the signs of factors. By understanding these concepts, students can predict graph behavior and identify regions where graphs will pass through.

What is the result when you multiply three positive numbers together?

• Positive

• Zero

• Undefined

• Negative

If you multiply a positive, a negative, and another positive number, what will the sign of the result be?

• Negative

• Zero

• Positive

• Undefined

What happens to the sign of the result when there is an odd number of negative numbers in a multiplication?

• The result is negative

• The result is zero

• The result is positive

• The result is undefined

When graphing, what does the line y = x - 4 represent?

• The x-axis

• The y-axis

• A factor of the graph

• The entire graph

How do two negative factors affect the graph's position on the axis?

• The graph is above the axis

• The graph is below the axis

• The graph is on the axis

• The graph is undefined

What is the result of multiplying a positive and a negative number?

• Positive

• Undefined

• Negative

• Zero

What happens to the graph when you cross a boundary where the sign changes?

• The graph disappears

• The graph changes direction

• The graph becomes undefined

• The graph remains unchanged

If all three factors are negative, what is the sign of the result?

• Negative

• Positive
