Algebra I Test Preparation Notes

Test Reminder: Unit 6: Quadratic Functions on April 28th

Key Topics to Review:

• Quadratic Functions of Projectiles: Understanding the coefficients' significance when launching an object.
• Vertex of Quadratics: Know the minimum or maximum point and whether the graph opens up or down.
• Equivalent Forms of Quadratics:
• Standard Form
• Factored Form
• Vertex Form
• Key information provided by each form.
• Graphing Quadratic Functions: Use a calculator to input the equation in Y=, generate a Table of Values, and plot points.
• Converting Factored Form to Standard Form: Use the FOIL or Box method for conversion.
• Equation of Axis of Symmetry: Understand that it is represented by the formula ( x = \text{number} ) where the number is the x-coordinate of the vertex.
