Question
Find the k value of vertex (h, k) for the equation .
- 23
- -23
- -2
- 2
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: -23
Adding on both the sides,

The other method to find the vertex of a parabola is as We know that the x-coordinate of a vertex, (i.e) h is -b/2a. Now, substitute the x-coordinate value in the given standard form of the parabola equation y=ax2+bx+c, we will get the y-coordinate of a vertex.
