Question

The table of values shows the height of a buoy compared to the sea floor over time as the tide goes in and out. This can be modeled by a sinusoidal function.

Which statements are true?
Select EACH correct answer

The maximum value of the function is 5.8

The amplitude of the function is 5.8

The period of the function is 24

The frequency of the function is 24

Answer 1

1st statement is true

2nd is false (amplitude is (max - min) ÷ 2 so (5.8 - 4.6) ÷ 2 = 0.6)

3rd is true

4th is false (frequency is the reciprocal of period, they can't be the same)
