Question

Как найти вершину параболы, если она не косается оси OX

Answer 1

Функция параболы: y=ax^2+bx+c; x вершины=-b/(2*a); а у - подставляешь x и находишь у;

Answer 2

Finding the Vertex of a Parabola

To find the vertex of a parabola when it does not touch the x-axis, you can use the formula (-b/2a, f(-b/2a)), where a and b are the coefficients of the quadratic equation in the form y = ax^2 + bx + c.

The x-coordinate of the vertex is given by -b/2a, and the y-coordinate can be found by substituting -b/2a into the equation to get f(-b/2a).

This method works for any parabola, whether it opens upwards or downwards.
