Question

how to find axis of symmetry?

Answer 1

Axis of symmetry of a parabola / quadratic function?

Answer 2

The general equation of a parabola is y = ax^2 + bx + c
The axis of symmetry will be the vertical line x = -b/(2a)

Answer 3

quadratic equation

Answer 4

The answer is in my second reply.

Answer 5

funtion

Answer 6

okay thank you so much

Answer 7

You are welcome.

Answer 8

You can use the quadratic equation. Take the two solutions and find their average:

\(\dfrac{(Solution1)+(Solution2)}{2} = -\dfrac{b}{2a}\)

Quite a remarkable thing and not a coincidence at all!

Answer 9

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.
