Answer:


(x,y) =(-4,-3) --- Vertex


x = -4 --- Axis of symmetry

Explanation:

Given


y = -6(x + 4)^2 - 3

Solving (a): The vertex

For an equation written in


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

The vertex is:


(x,y) = (h,k)

By comparison:


y = a(x - h)^2 + k and
y = -6(x + 4)^2 - 3


-h =4
k = -3


h =-4
k = -3

So, the vertex is:


(x,y) =(-4,-3)

Solving (b): The axis of symmetry

For an equation written in


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

The axis of symmetry is:

x = h

In (a):


h =-4

So:


x = -4
