PARABOLA - graph of a quadratic function.

Axis of Symmetry: vertical line through the vertex. (Created a mirror image) Vertex: The lowest or highest point of the quadratic function. (Maximum or Minimum) Y- Intercept: where the graph intersects the yaxis. X-Intercepts: where the graph intersects the x-axis. (Also called solutions or roots)
