Identify the parts of the cosine graph

The video tutorial covers the identification of graph characteristics, focusing on amplitude, period, and transformations. It explains how amplitude affects graph stretching and reflection, the concept of period and horizontal compression, and the role of the unit circle in determining graph limits. The tutorial also discusses vertical and phase shifts, range adjustments, and reflections about the X-axis, providing a comprehensive understanding of graph transformations.

What is the definition of amplitude in the context of graph transformations?

How does a horizontal compression affect the period of a graph?

Explain the significance of the unit circle in determining the maximum and minimum values of a graph.

What happens to the range of a graph when it is shifted down by one unit?

Describe the effect of a negative sign in front of a function on its graph.
