Exploring Sinusoidal Functions and Data Modeling

What type of function is used to model the data in this lesson?

• Quadratic function

• Sinusoidal function

• Exponential function

• Linear function

What is the maximum value identified in the data set?

• 225

• 98

• 50

• 100

What does the period of a sinusoidal function represent?

• The distance from the midline to the maximum

• The maximum value of the function

• The time it takes to complete one cycle

• The vertical shift from the midline

How is the frequency of a sinusoidal function calculated?

• Dividing the maximum by the minimum

• Multiplying the period by 2π

• Adding the period and the amplitude

• One over the period

What is the amplitude of the sinusoidal function discussed?

• 162.5

• 100

• 62.5

• 225

What is the midline value calculated in the lesson?

• 100

• 162.5

• 225

• 60

What phase shift is applied to the sinusoidal function model?

• No shift

• Shifted 20 units to the right

• Shifted 5 units to the right

• Shifted 5 units to the left

What is the value of 'B' in the sinusoidal function formula?

• π/60

• 2π/60

• π/30

• 30/π

Which tool is used to find a more precise sinusoidal model?

• A scientific calculator

• A graphing calculator

• A ruler

• A protractor

What does the sinusoidal regression function from the calculator show?

• A completely different function type

• No resemblance to the estimated model

• A slight variation from the estimated model

• An exact match with the estimated model
