Quadratic Functions Practice Companion
Now that you've explored the shape of quadratics and the art of completing the square, this is where you build fluency. Take your time. Get stuck if you need to — getting stuck is part of the work. There are four kinds of help on every question: a Socratic question (which asks you something rather than telling you), a hint (which gives you a piece of the method), a worked solution (which shows the whole thing), and an answer check.
Well done — you've worked through every question. 🌱
Take a moment for the reflection below. You can also press Ctrl+P (or ⌘+P) to print or save your work, including all the reveals and your written workings.
💛 Reflection
Mirroring the Living Body panel of the lesson: how did that feel? There are no wrong answers — these prompts are just to notice what's happening.
- Which question types felt natural? Which felt sticky?
- Did completing the square feel more mechanical or more meaningful by the end? Did the "why" behind it become clearer?
- When you had to find a maximum or minimum, did thinking about the vertex help, or did you reach for something else?
- On a scale of 1 (no clearer) to 5 (much clearer), how does your understanding of quadratic functions feel now compared to before this practice?
