    Answer:

    Vertex is (-4,3)

    Step-by-step explanation:

    rewrite the problem from y=-2(x+4)^2+3 to y=ax^2+bx+c

    y=-2x^2-16x-29

    the parabola points are: a=-2  b=-16  c=-29

    then divide x= -b/2(a)

    x= -(-16)/2(-2)

    simplify: x=-4

    go back and plug in x=-4 to get y

    y=3

    Answer is (-4,3)
