How to write the equation of a cubic function given the graph

The video tutorial covers identifying transformations in graphs, focusing on turning points, and understanding shifts to the right and upward. It explains the concepts of stretching, compressing, and reflection, and how these affect the graph's equation. The tutorial concludes with deriving the equation of a reflected graph and preparing students for a quiz.

What is the primary focus point when identifying transformations in a graph?

• The slope

• The turning point or vertex

• The y-intercept

• The x-intercept

If a graph is shifted to the right by 3 units, what is the value of H?

• 1

• 2

• 3

• 4

What is the value of K if a graph is shifted up by 1 unit?

• 0

• 3

• 1

• 2

How can you tell if a graph has been stretched?

• The graph's points are further apart vertically

• The graph moves right

• The graph moves left

• The graph's points are closer together vertically

What indicates a reflection in the graph's equation?

• A negative value of K

• A positive value of H

• A negative value of A

• A positive value of A
