Graphing Sine of X with Period Shift and Reflection Over X Axis

The video tutorial reviews quadratic functions, focusing on amplitude and period. It explains how to find critical points and graph sine functions, including transformations like reflection over the X-axis. The tutorial emphasizes understanding the parent graph and applying transformations to graph functions accurately.

What is the amplitude of a function if the coefficient 'a' is -1/2?

• 1/2

• -1/2

• 1

• 0

How do you calculate the period of a function with a coefficient B of 1/2?

• 1/2π

• 2π

• π

• 4π

What is the distance between critical points if the period is 4π?

• 4π

• 1/2π

• π

• 2π

What transformation occurs when the coefficient 'a' is negative?

• Vertical stretch

• Reflection over the x-axis

• Horizontal shift

• Reflection over the y-axis

If the amplitude of a graph is 1/2, how high does the graph go?

• 1

• 0

• 1/2

• -1/2

What is the period of the parent graph of sine?

• 1/2π

• π

• 2π

• 4π

How does a negative sign in front of the sine function affect the graph?

• It shifts the graph down

• It reflects the graph over the x-axis

• It reflects the graph over the y-axis

• It shifts the graph up
