# Test Description for Quadratic Equations and Functions

 SOL Objectives Number of Items Total For Mastery For Partial Mastery A2.6 Select, justify, and apply graphing and algebraic techniques to solve a quadratic equation. Model and solve real-life applications with quadratics. 5 4 N/A A2.8(2) Recognize a quadratic function and convert between a graph, a table and symbolic form. A transformational approach to graphing will be employed through the use of graphing calculators. 4 3 N/A A2.9(2) Find the domain, range, zeros, and inverse of quadratic functions. The functions will include those that have domains and ranges that are limited and/or discontinuous. The graphing calculator will be used as a tool to assist in investigation of functions. 4 3 N/A A2.10(1) Investigate and describe through the use of graphs the relationships between the solution of an equation, zero of a function, x-intercept of a graph, and factors of a quadratic expression. 5 4 N/A A2.19(2) Collect and analyze data to make predictions, write equations and solve practical problems. Graphing calculators will be used to investigate scatterplots to determine the equation for a curve of best fit. Models will include quadratic functions. 3 3 2 21
