  1. Consider the graph of the quadratic function. Identify the following properties of the parabola:

    • vertex
    • equation of the axis of symmetry
    • maximum or minimum value
    • x-intercept(s)
    • y-intercept
    • domain
    • range

    This shows a graph of a parabola going through points (–5, 0), (–1, –4), (0, –3.75), and (3, 0).
