Introduction to Quadratic Functions
Defining quadratic functions and exploring their basic properties, including vertex, axis of symmetry, and intercepts.
Key Questions
- Explain how the standard form of a quadratic function reveals its key graphical features.
- Analyze the impact of the leading coefficient on the concavity and stretch of a parabola.
- Predict the number of x-intercepts based on the graph of a quadratic function.
