Graph the Cosine Function with a Phase Shift

The video tutorial explains how to graph the cosine function with transformations. It covers key elements such as amplitude, period, X scale, phase shift, and vertical transformation. The instructor demonstrates graphing the parent cosine function and applying a phase shift to it, showing how the graph shifts π units to the right.

What is the amplitude of the cosine function described in the video?

• 2

• 1

• π

• 0

How is the period of the cosine function calculated?

• 2π / A

• 2π / B

• π / B

• B / 2π

What is the phase shift of the cosine function in the video?

• 0

• 2π

• π

• π/2

When graphing the parent function, where do we start?

• At the intercept

• At the minimum point

• At the maximum point

• At the vertex

What happens to the graph when a phase shift is applied?

• It shifts left or right

• It stretches vertically

• It reflects over the X-axis

• It compresses horizontally
