Three of given lines form a triangle with measures of two interior angles $79^{\circ}$ and $(2x+10)^{\circ}.$

The angle with measure $(6x+1)^{\circ}$ is exterior angle of considered triangle.

The measure of exterior angle of triangle is equal to the sum of the measures of two not adjacent interior angles:

$6x+1=2x+10+79,\\ \\6x+1=2x+89,\\ \\6x-2x=89-1,\\ \\4x=88,\\ \\x=22^{\circ}.$

Answer: correct choice is D

2(x^2+4x+4-4)+7= \\
2((x+2)^2-4)+7= \\
2(x+2)^2-8+7= \\
2(x+2)^2-1 \\ \\
\boxed{y=2(x+2)^2-1}$
