Explanation

The standard form of a quadratic equation is the following:

[tex]y=ax^2+bx+c[/tex]

Where a, b and c are numbers. In this case we are given a quadratic equation in vertex form:

[tex]y=(x-4)^2-16[/tex]

We can expand the squared binomial:

[tex]\begin{gathered} y=x^2-2\cdot4\cdot x+(-4)^2-16 \\ y=x^2-8x+16-16 \\ y=x^2-8x \end{gathered}[/tex]Answer

Then the answer is the second option.
