How to determine the max or min of a quadratic function in vertex form

The video tutorial explains how to rewrite functions to understand transformations, focusing on identifying the vertex in equations. It highlights the importance of recognizing the vertex as H, K and discusses how to determine if a graph has a maximum or minimum based on its direction and reflection about the X-axis.

What is the primary reason for rewriting equations in a specific format?

• To change the equation's meaning

• To easily identify transformations

• To make them look more complex

• To confuse the students

In the context of graph equations, what does the vertex represent?

• The slope of the graph

• The highest point of the graph

• The intersection with the y-axis

• The point H, K in the equation

If the vertex of a graph is at H, K, what does H represent?

• The y-intercept of the graph

• The y-coordinate of the vertex

• The x-coordinate of the vertex

• The slope of the graph

How can you determine if a graph has a maximum or minimum point?

• By looking at the color of the graph

• By counting the number of vertices

• By observing if the graph opens upwards or downwards

• By checking if the graph is reflected about the y-axis

What happens to the vertex when the graph is reflected about the x-axis?

• It becomes a minimum point

• It disappears

• It becomes a maximum point

• It remains unchanged
