Horizontal Compression and Graph Transformations

The video tutorial covers function transformations, including reflection, horizontal compression, and vertical shifts. It explains how to identify these transformations in equations and apply them to graphing. The tutorial also discusses determining the domain and range of transformed functions.

What is the purpose of identifying the parent function in transformations?

• To find the function's intercepts

• To calculate the function's range

• To understand the basic shape before transformations

• To determine the function's domain

What is the significance of the parent graph in transformations?

• It helps in identifying the domain

• It serves as a reference for transformations

• It determines the range

• It is used to find intercepts

What happens when you multiply inside a function by a negative number?

• The graph reflects over the y-axis

• The graph reflects over the x-axis

• The graph shifts up

• The graph compresses horizontally

What does a reflection over the y-axis imply?

• The graph is flipped horizontally

• The graph is shifted to the right

• The graph is compressed

• The graph is flipped vertically

What is the result of multiplying a function by a negative number?

• The graph shifts up

• The graph stretches vertically

• The graph reflects over the y-axis

• The graph compresses horizontally

What does a horizontal compression involve?

• Shifting the graph to the right

• Stretching the graph vertically

• Reflecting the graph over the x-axis

• Squishing the graph horizontally

How is the factor of horizontal compression determined?

• By the slope of the line

• By the y-intercept

• By the absolute value of the coefficient inside the function

• By the coefficient of x

What is the effect of a horizontal compression factor of 2?

• The graph stretches horizontally by a factor of 2

• The graph compresses horizontally by a factor of 2

• The graph shifts vertically by 2 units

• The graph reflects over the x-axis

What does the absolute value of a negative coefficient inside a function indicate?

• The vertical shift

• The horizontal compression factor

• The horizontal stretch factor

• The direction of the graph
