MASTER how to find the vertex and determine domain and range of a quadratic in vertex form

The video tutorial explains how to identify the vertex of a quadratic equation in vertex form, compares it with standard form, and discusses the domain and range of quadratic functions. It provides multiple examples to illustrate different scenarios, including positive and negative coefficients, fractional values, and radicals in the vertex.

What is the significance of the values H and K in the vertex form of a quadratic function?

What is interval notation and how is it used to express the range of a quadratic function?

Describe how the graph of a quadratic function changes when the vertex is shifted.

How can you identify the maximum or minimum point of a quadratic function?
