Answer:
Step-by-step explanation:
If we want to find the axis of symmetry of the parabola of [tex]y=-4x^{2} -8x-7,[/tex] we would use the formula of [tex]-\frac{b}{2(a)}[/tex] to find it.
b=-8
a=-4
so the formula would look like this [tex]-\frac{-8}{2(-4)}[/tex], simplify it >>>[tex]-\frac{-8}{-8}[/tex] which is -1
So -1 would be the axis of symmetry
