Question

what is the green dashed line called? options: parabola, axis of symmetry, line of dashes, roots or x - intercepts (with an image of a parabola on a coordinate plane showing the green dashed line)

Explanation:

The green dashed line divides the parabola into two mirror-image halves, a defining feature of quadratic graphs. The other options are incorrect: the parabola is the curved graph itself, roots/x-intercepts are the points where the graph crosses the x-axis, and "line of dashes" is not a mathematical term for this feature.

Answer:

axis of symmetry
