3.1: Quadratic Functions WORKSHEET
Pre-Calculus 11 Name: _________________________ 3.1: Quadratic Functions WORKSHEET 1. Graph each of the following functions by comparing to y x 2 with a new (p,q) value and state the required information. Check with a graphing calculator or table of values if needed. y ( x 3)2 y x2 2 Vertex Vertex Axis of symmetry Domain Axis of symmetry Domain Range Range Y-intercept Y-intercept X-intercept(s) X-intercept(s) y ( x 4)2 3 y ( x 1)2 2 Vertex Vertex Axis of symmetry Domain Axis of symmetry Domain Range Range Y-intercept Y-intercept X-intercept(s) X-intercept(s) 2. Given the following graphs, find the required information. Write a function for the graph in the form y ( x p)2 q . Vertex Vertex Axis of symmetry Domain Axis of symmetry Domain Range Range Y-intercept Y-intercept X-intercept(s) X-intercept(s) Equation: __________________ Equation: __________________ 3. Draw a sketch of a quadratic function with the given information. a) vertex at (3,-2), y-intercept at 7 b) x-intercepts at -3 and 1, y-intercept at 1 4. Search “Quadratic Function Applications” on GOOGLE and list at least two real-life examples of quadratic functions. You do not need to write any details about the application, just the topic itself.
