Answer:

[tex]\frac {4 \times (y - 7)}{8} = (x -3)^{2}[/tex]

The equation is represented by a parabola.

so, the vertex of the parabola is at (3, 7)

Step-by-step explanation:

The equation is represented by a parabola. The equation is,

  y = [tex]2x^{2} - 12x +25[/tex]  (given)

  ⇒ y = [tex]2(x^{2} - 6x +9) + 7[/tex]

  ⇒ (y - 7) = [tex]2(x -3)^{2}[/tex]

  ⇒ [tex]\frac {4 \times (y - 7)}{8} = (x -3)^{2}[/tex]

so, the vertex of the parabola is at (3, 7)
