How do you find the axis of symmetry?
Understand the Problem
The question is asking for the method to determine the axis of symmetry, which is typically related to quadratic functions or parabolas. The axis of symmetry can be found using the formula or by understanding the properties of the graph.
Answer
x = -b / (2a)
The formula for the x-coordinate of the axis of symmetry is x = -b / (2a).
Answer for screen readers
The formula for the x-coordinate of the axis of symmetry is x = -b / (2a).
More Information
The axis of symmetry is a vertical line that divides a parabola into two mirror images. It helps in graphing the quadratic equations and finding the vertex of the parabola.
Tips
A common mistake is to use the wrong sign when calculating -b / (2a). Ensure all arithmetic operations follow the correct order of operations.
