Graphs of quadratic functions: Graphs of quadratic functions Suggested resource/activity from MEI scheme of work Autograph Casio Desmos GeoGebra Problem solving (AS) Problem-solving with Geogebra: Construction Problems: Surds and indices (AS) Sumaze! Power Maze: Quadratic functions (AS) Enter y=ax 2 +bx+c into a graph plotter and vary a, b and c.There are loads of different roller coaster types - not just "wood" and "steel". We did a polynomial function discovery activity (via Jon Orr) in Desmos, giving students a chance to scale up prior knowledge, extending a pattern from quadratic to cubic, and theoretically beyond.Borrowed generously from Mary Bourassa's Quadratic Transformations - Part 1 and Part 2, in order to create a one-day activity Quadratic Transformations - Part 1: https.Examples of Quadratic Functions where a ≠ 1: y = -1x 2 (a = -1) y = 1/2x 2 (a = 1/2) y = 4x 2 (a = 4. When the a is no longer 1, the parabola will open wider, open more narrow, or flip 180 degrees. Another form of the quadratic function is y = ax 2 + c, where a≠ 0 In the parent function, y = x 2, a = 1 (because the coefficient of x is 1).Watch the short video in the Minds On section of the activity for help. For some equations, you will estimate the x-intercepts from the desmos graph and add points to the graph. Using some of the quadratic relations, you will determine some intercepts algebraically and check the values using desmos.
