Answer:
well the answer will come out to 9272
Step-by-step explanation:
Given:
The equation of a parabola is:
To find:
The coordinates of the vertex of the given equation.
Solution:
The vertex form of a quadratic function is:
...(i)
Where, a is a constant and (h,k) is the vertex.
We have,
...(ii)
On comparing (i) and (ii), we get
We know that the vertex of the parabola is (h,k).
Therefore, the vertex of the given equation is (-2,-1).
