Answer:
Axis of symmetry
Step-by-step explanation:
The maximum or minimum point on the parabola is the vertex
To cut the parabola into two congruent halves, we use vertex
A vertical line that crosses the vertex cuts the parabola in two halves.
The vertical line that crosses the vertex is called as axis of symmetry.
So, the axis of symmetry is the line that cuts a graph of a quadratic function in half.
