How do you find the vertex of a quadratic equation?
To find the vertex of a quadratic equation, y = ax2 + bx + c, we find the point (-b / 2a, a(-b / 2a)2 + b(-b / 2a) + c), by following these steps.
Get the equation in the form y = ax2 + bx + c.
Calculate -b / 2a.
This is the x-coordinate of the vertex.

How do you find the vertex form of a parabola?
f (x) = a(x – h)2 + k, where (h, k) is the vertex of the parabola. FYI: Different textbooks have different interpretations of the reference “standard form” of a quadratic function. Some say f (x) = ax2 + bx + c is “standard form”, while others say that f (x) = a(x – h)2 + k is “standard form”.
WHAT IS A in vertex form?
The vertex form of a quadratic is given by. y = a(x – h)2 + k, where (h, k) is the vertex. The “a” in the vertex form is the same “a” as. in y = ax2 + bx + c (that is, both a’s have exactly the same value). The sign on “a” tells you whether the quadratic opens up or opens down.

What is axis symmetry?
The graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
