Solving Quadratic Equations by GraphingVideos, worksheets, games and acivities to help Algebra students learn about how to solve quadratic equations by graphing.
Solving Quadratic Equations by Graphing Part 1 This video demonstrates how to solve quadratic equations by graphing. First, a quadratic equation is converted into a quadratic function. Then, the variables are changed to x and y to graph on a coordinate plane. The solutions are shown where the function crosses the x-axis. Roots, x-intercepts, and zeros are given as synonyms for solutions. Finding roots from a table of values is also demonstrated.
Solving Quadratic Equations by Graphing Part 2 This video shows how to solve quadratic equations using the TI84 and TI83 series of graphing calculators. Five problems are worked out. The different steps are shown including converting quadratic equations into calculator ready graphable quadratic functions. The video shows how to examine in graph and table view what the solutions are. The case of having no solutions is shown as well as that of having only one solution.
Graphing quadratic equations Graphing a parabola from an equation in standard form. Includes x-intercept, y-intercept, vertex, and axis of symmetry.
