Video Learning Notes

In this lesson, students learned to graph quadratic functions on the coordinate plane and identify key attributes including x-intercepts, y-intercept, zeros, vertex, axis of symmetry, and maximum or minimum values. They connected the algebraic form of quadratic expressions, especially their linear factors, to the zeros of the function. Through guided practice, real-world examples, and independent tasks, students developed skills to analyze and interpret quadratic graphs effectively.

Learning Goals

• Graph quadratic functions on the coordinate plane using key points and features.
• Identify the x-intercepts, y-intercept, zeros, vertex, maximum or minimum values, and axis of symmetry from the graph of a quadratic function.
• Describe how the linear factors of a quadratic expression relate to the zeros of its quadratic function.
