Question

The vertex of the parabola below is at the point (1, -3). Which of the equations below could be the one for this parabola?

Answer 1

Apex answer is: B y=(x-1)^2-3

Explanation:

Answer 2

Any answer choice in the form
`y=a(x-1)^2-3`

Explanation:

To write the quadratic equation, begin by writing it in vertex form

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

Where (h,k) is the vertex of the parabola.

Here the vertex is (1,-3). Substitute and write:

`y=a(x-1)^2+-3\\y=a(x-1)^2-3`
