What is the function F(x)= 4x^2+16x+8 vertex?
------------------------------------------------

For the quadratic function = x-coordinate of the vertex is = .

In this case it is = = -2.

To determine the y-coordinate of the vertex, substitute this value of = -2 into the quadratic function. You will get

= = 4*4 - 32 + 8 = -8.

So, the vertex is (x,y) = (-2, -8).
