The Axis of Symmetry is very important for understanding parabolas. Here’s why:
What It Is: The Axis of Symmetry is a straight vertical line. It splits the parabola into two equal halves that look like mirror images.
How to Find It: You can find the Axis of Symmetry using this formula:
( x = -\frac{b}{2a} )
In this formula, ( a ) and ( b ) come from the quadratic equation:
( y = ax^2 + bx + c )
Finding the Vertex: This Axis meets the parabola at its vertex. You can find the vertex's position using this formula for the ( y )-coordinate:
( k = f(-\frac{b}{2a}) )
Finding Points: Knowing the Axis of Symmetry helps you find both the x-intercepts and the y-intercept. This makes it easier to understand the entire graph.
In short, the Axis of Symmetry helps us better understand the shape and important points of parabolas!
