Identify the parts of the sine graph

The video tutorial covers the basics of graphing, focusing on identifying key graph components such as amplitude, period, phase shift, and vertical transformation. It explains how to determine the domain and range of a graph, emphasizing the importance of understanding these concepts for answering related questions. The tutorial also highlights the use of abbreviations for tests and quizzes.

What is the amplitude of a graph if the function is multiplied by 2?

• 3

• 2

• 0.5

• 1

How often does a sine or cosine graph repeat itself?

• Every π

• Every 4π

• Every 2π

• Every π/2

What happens to a graph when a constant is added inside the function?

• It shifts vertically

• It shifts horizontally

• It stretches

• It compresses

If a graph is shifted up by one unit, what is the new range if the original range was from -1 to 1?

• -2 to 0

• -1 to 1

• 1 to 3

• 0 to 2

Why are brackets used instead of parentheses when denoting the range of a graph?

• To exclude the endpoints

• To include the endpoints

• To show the range is exclusive

• To indicate open intervals
