 Lesson Objective(s)
Standard(s)  Graphing Quadratic Functions
 CC.912.F.IF.7a Graph linear and quadratic functions and show intercepts, maxima, and minima.
 Solving Quadratic Equations
 CC.912.A.REI.4 Solve equations and inequalities in one variable. Solve quadratic equations in one variable.
 CC.912.A.REI.4b Solve quadratic equations by inspection (e.g., for x^2 = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.
 Factored Form
 CC.912.A.SSE.3a Factor a quadratic expression to reveal the zeros of the function it defines.
 CC.912.F.IF.8a Use the process of factoring and completing the square in a quadratic function to show zeros, extreme values, and symmetry of the graph, and interpret these in terms of a context.
 Completing the Square
 CC.912.A.SSE.3b Complete the square in a quadratic expression to reveal the maximum or minimum value of the function it defines.
 CC.912.A.REI.4a Use the method of completing the square to transform any quadratic equation in x into an equation of the form (x – p)^2 = q that has the same solutions. Derive the quadratic formula from this form.
 CC.912.F.IF.8a Use the process of factoring and completing the square in a quadratic function to show zeros, extreme values, and symmetry of the graph, and interpret these in terms of a context.
 Quadratic Formula

 Creating Quadratic Equations
 CC.912.A.CED.1 Create equations that describe numbers or relationship. Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.
 Comparing Quadratics Function with Different Representations
 CC.912.F.IF.9 Analyze functions using different representations. Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a graph of one quadratic function and an algebraic expression for another, say which has the larger maximum.
 Quadratic Modeling
 CC.912.F.LE.1 Construct and compare linear, quadratic, and exponential models and solve problems. Distinguish between situations that can be modeled with linear functions and with exponential functions.
 CC.912.S.ID.6a Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear, quadratic, and exponential models.
 Complex Solutions of Quadratic Functions
 CC.912.N.CN.7 Use complex numbers in polynomial identities and equations. Solve quadratic equations with real coefficients that have complex solutions.
 CC.912.A.REI.4b Solve quadratic equations by inspection (e.g., for x^2 = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.
