What’s on the Anatomy of a Parabola poster
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.

- 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.
