Changes in Period and Phase Shift of Sine and Cosine Functions

Question 19 • AZ-Common Core Algebra II B

Which did you include in your response

Answer

A cosine function would be a simpler model for the situation.

The minimum depth (low tide) occurs at t = 0. A reflection of the cosine curve also has a minimum at t = 0.

A sine model would require a phase shift, while a cosine model does not.
