Question
The coordinates of the vertex of the parabola whose equation is 
are:
- (2, 11)
- (-1, -7)
- (1, 1)
- (-2, -6)
Hint:
In this question, we have to find the k value of vertex (h, k) for the equation . Vertex form is another form of a quadratic equation. The standard form of a quadratic equation is a
+ bx + c. The vertex form of a quadratic equation is a 
+ k where a is a constant that tells us whether the parabola opens upwards or downwards, and (h, k) is the location of the vertex of the parabola.
The correct answer is: (-2, -6)
Given quadratic equation,
Now we isolate constants to the other side,
Adding 4 on both sides, we get
The vertex form of the quadratic equation is 
.
Therefore, vertex is (-2, -6).
