Build Your Own Functions Map

Turn your lesson notes or textbook chapter into a clear map of functions and their connections.

Build from your notes

Upload a PDF, Word file, slides or text, and the AI pulls out the key ideas about functions.

See how the topic fits together

Branches link domain, range, graphs and transformations so you can see how each idea depends on the others.

Quiz yourself from the map

Turn the finished map into a quiz, or make flashcards from the same notes for quick review.

How to Make a Functions Map

Three steps from your class material to a study map you can expand and test yourself with.

1
Add your material
Upload your notes or chapter, or type the topic such as functions and domain.
2
AI builds the map
The AI organizes the topic into branches with expandable nodes you can edit.
3
Study, expand or quiz
Expand weak areas, export as PNG or PDF, or turn the map into a quiz.

Functions Concept Map: Key Ideas and Branches

A function is a rule that gives exactly one output for each input. A functions concept map organizes this idea into branches: the definition and notation, the domain and range of a function, how functions are represented as equations, tables and graphs, and how they change through transformations and inverses. Seeing these links helps you move between representations with confidence.

Definition and notation: input, output and f(x) form
Domain and range: allowed inputs and resulting outputs
Representations: equations, tables, graphs and mappings
Transformations: shifts, stretches and reflections of graphs
Inverses: reversing a function and checking with composition

Use the map to revise before a test, spotting which branch you cannot yet explain. Create a personalized functions map from your own notes with CogniGuide to focus your study time.

Functions Concept Map Questions

Answers about the main ideas and how to build your own map.

What is the difference between domain and range?

The domain is the set of all input values a function can accept. The range is the set of all output values the function can produce. For example, f(x) = x squared has domain all real numbers and range all values zero or greater.

How do you know if a graph is a function?

Use the vertical line test. If any vertical line crosses the graph more than once, the graph does not represent a function, because one input would give two outputs.

Which file types can I use to build a functions map?

You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images of your notes. You can also type the topic directly.

Can I turn my functions map into a quiz?

Yes. Once the map is built, you can turn it into a quiz to test yourself. There is also a free plan with 5 creations a week.
