Example Question #411 : High School: Functions
What is the vertical shift of the function?
This question is testing one's ability to identify the periodicity of a trigonometric function. This requires the understanding of trigonometric functions and their graphical and algebraic characteristics.
For the purpose of Common Core Standards, "Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline" falls within the Cluster B of "Model Periodic Phenomena with Trigonometric Functions" concept (CCSS.MATH.CONTENT.HSF-TF.B.5).
Knowing the standard and the concept for which it relates to, we can now do the step-by-step process to solve the problem in question.
Step 1: Write the general form of trigonometric shifts.
where
Step 2: Algebraically identify the vertical shift.
Given the function
identify the variables of the general form.
Step 3: Graph the trigonometric function to verify.
The graph above verifies that the vertical shift of the function is .
