Graph of a Quadratic Function – Parabola Equation for a Quadratic y-intercept Equation of the Axis of Symmetry x-coordinate of the Vertex -3

4
Maximum and Minimum Value Equation for a Quadratic Opens up and has a Minimum Opens Down and has a Maximum

5
Complete parts a-e for the each quadratic function. a. Find the y-intercept, the equation of the axis of symmetry, and the x-coordinate of the vertex. b. Make a table of values that includes the vertex. c. Use this information to graph the function. d. Determine whether each function has a maximum or minimum value, and find that value. e. State the domain and range of the function.
