    Lessons

    Lesson 1: Exploring a Situation Using a Quadratic Function

    Not started

    Use tables, scatter plots and second differences to recognize quadratic situations, build simple models, make predictions and choose sensible domains.

    Lesson 2: Relating the Standard and Factored Forms

    Not started

    Move between f(x) = ax² + bx + c and f(x) = a(x − r)(x − s), and use each form to find zeros, the axis of symmetry, the vertex and the y-intercept.

    Lesson 3: Solving Quadratic Equations by Graphing

    Not started

    Read solutions from a graph, compare zeros with intersections, check by substitution, and choose meaningful answers in context.

    Lesson 4: Solving Quadratic Equations by Factoring

    Not started

    Connect factors to graph roots, solve with the zero-product property, keep every solution, and interpret break-even points.
