Aparabola with vertex (h, k) and a vertical axis of symmetry is modeled by the equation y - k = a(x - h)2. determine the vertex for a parabola modeled by y = (x ? 5)2 + 8 a) (5, 8) b) (? 5, 8) c) (5, ? 8) d) (? 5, ? 8)

B.

Step-by-step explanation:

We have been given a parabola with vertex (h, k) and a vertical axis of symmetry is modeled by the equation .

We are also given a parabola .

Let us convert our given parabola equation in axis of symmetry equation as shown below:

Upon comparing our equation with equation , we can see that and .

Therefore, the vertex of the parabola is and option B is the correct choice.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal
