How to determine the axis of symmetry and vertex

The video tutorial covers solving a quadratic equation by finding the axis of symmetry and the vertex. It begins with an introduction to the problem and context, followed by an explanation of the quadratic equation components. The tutorial then demonstrates how to calculate the axis of symmetry using the formula x = -b/2a and proceeds to find the vertex by substituting the x-coordinate into the equation. The vertex is identified as a coordinate point, representing either the maximum or minimum of the parabola.

What is the vertex of the parabola represented by the quadratic equation?

Explain the significance of the vertex in a parabola.
