Answer: the vertex form is y=(x+4)^2+-19
Step-by-step explanation: correct on E2020
The vertex form of the function is [tex]y=(x+4)^{2}-19[/tex]
The vertex form of the equation is written as,
[tex]y=(x+h)^{2}+k[/tex]
Given function is,
[tex]y=x^{2} +8x+16-3-16[/tex]
It is observed that, [tex]x^{2} +8x+16=(x+4)^{2}[/tex]
So that, we can write as above function,
[tex]y=(x+4)^{2}-3-16\\ \\y=(x+4)^{2}-19[/tex]
