Find two quadratic functions whose graph have given x-intercepts. Find one function whose graph opens upward and another whose graph opens downward.
(-4,0) (0,0)

  • MATH -

    from the values of the roots, we know that the functions will be of the form

    y = ax(x+4)

    So, pick a positive to open upward, and a negative to open downward.

    Any nonzero value will do.
