Parabola Axis of Symmetry: Example 7

Quadratics

Description

The axis of symmetry is a vertical line that passes through the vertex of a parabola, dividing it into two mirror-image halves. For a quadratic function in the form f(x) = ax² + bx + c, the axis of symmetry can be calculated using the formula x = -b / (2a), where 'a' and 'b' are the coefficients of the quadratic equation.

In this example, we have the quadratic function f(x) = 2x² + 4x + 10. To determine the axis of symmetry, we use x = -b / (2a). Here, a = 2 and b = 4. Calculating, we get x = -1. The axis of symmetry is therefore x = -1. This line passes through the vertex of the parabola, dividing it into two symmetrical halves.
