## symmetry over x-axis

### Symmetry over the x-axis is a property in mathematics where a figure or graph is identical on both sides of the x-axis

Symmetry over the x-axis is a property in mathematics where a figure or graph is identical on both sides of the x-axis. In other words, if a point (x, y) lies on the graph, then the point (x, -y) will also lie on the graph.

To understand this concept visually, imagine a graph on a coordinate plane. The x-axis is the horizontal line that cuts through the center of the graph. If a figure or graph is symmetric over the x-axis, it means that if you were to fold the graph along the x-axis, the two halves would perfectly match and coincide with each other.

For example, consider the graph of a quadratic function y = x^2. As we plot the points on the graph, we can notice that each point (x, y) has a corresponding point (x, -y) reflected across the x-axis. This shows the symmetry over the x-axis.

Symmetry over the x-axis is an essential concept in mathematics and can be used to simplify calculations. By knowing that a graph is symmetric over the x-axis, we can make predictions about the behavior of the graph without having to analyze the entire graph.
