Answer:

Step-by-step explanation:

No. y = - (x + 2) + 4 is not even a quadratic.

If you want a quadratic you must indicate squaring: y = - (x + 2)^2 + 4.

This IS in vertex form; the vertex is at (-2, 4).

Answer:

$\mathrm{C)\:}x=15,\:-7$

Step-by-step explanation:

For $|a-b|=c$ , there are two possible cases:

$\begin{cases}a-b=c\\a-b=-c\\\end{cases}$

Solving for both cases, we get:

$\begin{cases}x-4+6=17, \:x+2=17, \: \fbox{$x=15$}\\-(x-4)+6=17,\: -x+10=17, \: -x=7, \:, \fbox{$x=-7$}\\\end{cases}$
