Question

Vertex (3,-2) and y-intercept (0,7).

Write your answer in this form: (X₁,Y1), (X2,2).
If necessary, round to the nearest hundredth.
Enter the correct answer.

Answer 1

3±√2/3 = x

Explanation:

As you already have the vertex, the equation for this is y = a(x – h)^2 + k,

so by plugging all this in using the vertex coordinates, you get y = 3(x - 3)^2-2, so, if you divide everything by three you get 2/3 = (x - 3)^2

This means that the two x-intercepts are:
