    See below in bold.

    Step-by-step explanation:

    y = 3 (x + 2) (x + 6)

    3 (x + 2) (x + 6) = 0

    x = - 2, - 6.

    The x - intercepts are (-2,0) and (-6, 0).

    Convert to vertex form:

    y=3 (x + 2) (x + 6)

    y = 3 (x^2 + 8x + 12)

    y = 3 (x^2 + 8x) + 36

    y = 3[ (x + 4) ^2 - 16] + 36

    y = 3 (x + 4) ^2 - 12.

    So the vertex is at (-4, - 12) and

    the axis of symmetry x = - 4.
