Unit #6 - Quadratic Functions
I can:
-evaluate a quadratic function for given values - both positive and negative. (T1)
-describe the changes to the graph of y=x^2 in terms of translations, reflections, and dilations. (T2)
-write a quadratic function that describes a quadratic relationship between two quantities. (T3)
-compare properties of two quadratic functions each represented in a different way (graph, table, verbal model, or algebraic expression) and determine the practical domain of a quadratic function based on real world context. (T4)
-graph quadratic functions given a verbal description or expressed symbolically, showing key features including: intercepts; intervals where the function is increasing, decreasing, positive, or negative; maximums or minimums; symmetries; end behavior; values for the vertex; and the axis of symmetry.
