Answer:

Hi!

The correct answer is y =x^2 - 4x + 2

Step-by-step explanation:

The axis of symmetry is the x-coordinate vertex of the parabola.

The general form to find the axis of symmetry is:

[tex]x=-\frac{-b}{2*a} [/tex]

For y =x^2 - 4x + 2, a=1, b=−4 and c=2:

[tex]x=-\frac{-4}{2*1} = - \frac{-4}{2} = -(-2) = 2[/tex]

[tex]x = 2[/tex]
