Graphing Quadratics

Topics

• Graphing
• Parabola
• Quadratic Function
• Vertex

Description

Discover how changing coefficients changes the shape of a curve. View the graphs of individual terms (e.g. y=bx) to see how they add to generate the polynomial curve. Generate definitions for vertex, roots, and axis of symmetry. Compare different forms of a quadratic function. Define a curve by its focus and directrix.

Sample Learning Goals

• Describe how changing the coefficients of a quadratic function changes the graph of the function.
• Predict how the graph of a parabola will change if the coefficients or constant are varied.
• Identify the vertex, axis of symmetry, roots, and directrix for the graph of a quadratic equation.
• Use the vertex form of a quadratic function to describe the graph of the function.
• Describe the relationship between the focus and directrix and resulting parabola.
• Predict the graph of a parabola given a focus and directrix.
