Find two quadratic functions, one that opens upward and one that opens downward, whose graphs have the given x-intercepts.

(-3, 0), (-1/2, 0)

  • Math -

    Quadratic functions that have given x-intercepts x1 and x2 are given by the equation:
    y=a(x-x1)(x-x2)

    If a>0, the curve opens upwards, and if a<0, the curve opens downwards.
    |a| can be any value ≠0 depending on the location of the vertex or any other point on the curve.
