    x=-3

    Step-by-step explanation:

    f (x) = - 2 (x + 3) ^2 - 5

    This quadratic is in the form

    f (x) = a (x - h) ^2 + k

    f (x) = - 2 (x - - 3) ^2 + - 5

    Where (h, k) is the vertex

    (-3,-5)

    We know the axis of symmetry is along the vertex

    x=h is the axis of symmetry

    x=-3
