2. 5.1 graph quadratics Objective: To graph quadratic functions. Where do you find these functions?

3. 5.1 graphing quadratics The graph of a quadratic function Y-intercepty value when x=0 or c in the equation vocabulary

4. Graphing Quadratic Equations 1) How do you do it? 2) Example Step 1: Find the vertex. will give you the x-coordinate of the vertex. Plug back in to find the y-coordinate. Step 2: Make a table of value (2 above and 2 below the vertex) Step 3: Find the y-intercept (plug in x=0 or c) 1) 2)
