Find the axis of symmetry and vertex for the parabola y=-4x^2-32x-10

Axis of Symmetry: x = -4

Vertex: (-4, 54)

Step-by-step explanation:

We use a graphing calc.

the equation of the axis of symmetry is

Step-by-step explanation:

Recall that the x-value of the vertex of a parabola of the form:

is given by the expression:

therefore, in our case the x-position of the vertex becomes;

and since the equation of the axis of symmetry is

Then, the equation of the axis of symmetry is
