To find the vertex of the quadratic function , we can use the vertex formula.

Vertex Formula

For a quadratic in the form , the x-coordinate of the vertex is given by:

 

Applying the Formula

In the equation :

a = -4

b = -16

 

Calculating the x-coordinate of the vertex:

 

Now, substitute x = -2 back into the equation to find the y-coordinate:
