Phase shifts of trigonometric functions

What happens to the graph of y = a sin(BX - C) when C is positive?

• The graph shifts upwards.

• The graph does not shift.

• The graph shifts to the left.

• The graph shifts to the right.

How does the coefficient B affect the graph of a trigonometric function?

• It changes the amplitude.

• It affects the phase shift and period.

• It has no effect on the graph.

• It shifts the graph vertically.

What is the formula for calculating phase shift when B is not equal to 1?

• C multiplied by B

• C divided by B

• B divided by C

• C plus B

In the example y = 3 sin(2X - π/2), what is the correct phase shift?

• π/2 to the right

• π/4 to the right

• π/2 to the left

• π/4 to the left

Why is it important to divide C by B when calculating phase shift?

• To determine the amplitude

• To find the correct direction and magnitude of the shift

• To calculate the period

• To adjust the vertical shift
