Question

Write in vertex form a quadratic that has vertex of (7, 9)

Options in image.

Answer 1

Choice A is the answer.

Explanation:

We have given a vertex of a equation.

vertex = (h,k) = (7,9)

We have to find the quadratic in vertex form.

The quadratic equation in vertex form is:

y = (x-h)²+k where (h,k) is vertex.

Putting given values in above formula, we have

y = (x-7)²+(9)

y = (x-7)²+9 is the quadratic equation in vertex form where (7,9) is vertex.

Answer 2

First option

`y = (x-7) ^ 2 + 9`

Explanation:

In this case we must write a quadratic equation in the vertex form.

We have the vertice. (7, 9)

We know that the vertex form for a quadratic equation is:

`y = (x-h) ^ 2 + k`.

Where (h, k) is the vertex.

So if the vertex is (7, 9), the equation sought is:

`y = (x-7) ^ 2 + 9`

Therefore the answer is the first option.
