The rule, 4 worked examples. Every quadratic graphs as a parabola. Its key features come straight from a, b and c.; axis: x = −b/2a; a > 0 = opens upward; a < 0 = opens downward; y-intercept = c; Vertex = x = −b/2a, then substitute. Roots, zeros, solutions and x-intercepts all mean the same thing. Different words, one idea.

Anatomy of a Parabola is filed under 9th Grade (ages 14–15), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.
When should you use the Anatomy of a Parabola poster?
Find the axis of symmetry first. The vertex sits on it, and the graph mirrors across it. A wall chart earns its place by being glanceable from where the work is happening, so Anatomy of a Parabola belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
