How do we find the period of the sinusoidal function below?
f(x) = asin(kx)+d

Find the equation of the midline of the graph shown.

• y = 1

• y = 2

• y = 3

• y = 0

Find the amplitude of the graph shown.

• 2

• 4

• 6

• 8

Match the following

• Graph 4

• Graph 1

• Graph 3

• Graph 2

F(x) = Asin[B(x-C)] + D is the standard form. A is the Amplitude B helps you find the period, B=2pi/period C is the phase shift D is the vertical shift Then f(x) = 2Sin(3x + 1) + 4

• 4

• vertical shift

• 1

• helps calculate period

• 3

• phase shift

• 2

• amplitude

For y=7sin(6(x-8))+9, What is the value of A, B , C, and D?

• 8

• C, phase shift

• 6

• D, midline

• 9

• A, amplitude

• 7

• B, helps calculate period

What is the equation of the graph?

• y = - 6 cos x - 1

• y = 3 cos x - 4

• y = -7 cos x 

• y = -3 cos x - 4 

What is the equation of the graph?

•  y = 2 cos x

• y = sin x

• y = 2 sin x

• y = sin 2x 

y=Asin(B(x-C))+D is the standard form. A is the Amplitude B helps you find the period, B=2pi/period C is the phase shift D is the midline (vertical shift) For y=7sin(6(x-8))+9,

• 6

• A, amplitude

• 8

• D, midline

• 9

• C, phase shift

• 7

• B, helps calculate period
