• 5

• 0

• -5

How do you calculate the period of a trigonometric function?

• B multiplied by 2π

• B divided by 2π

• 2π divided by B

• 2π multiplied by B

What is the X scale if the period is 2π/3?

• π/6

• π/3

• π/12

How do you find the phase shift of a function?

• Set the function equal to π

• Set the inside of the function equal to 0

• Set the function equal to 1

• Set the inside of the function equal to 1

What happens to the graph if you add 0.5 outside the function?

• It shifts down 0.5

• It shifts up 0.5

• It shifts left 0.5

• It shifts right 0.5
