Answer 1

I will re-write in the equation for you in a standard form.

\(\normalsize\color{blue}{ y = x^2 - 4x + 6}\)
\(\normalsize\color{blue}{ y = x^2 - 4x + 4+2 }\)
\(\normalsize\color{blue}{ y = (x-2)^2+2 }\)

Answer 2

I want some effort on your behalf, please.

Answer 3

I would just plug in the options, and only 1 choice would work.
