1. Key Ideas

Look at a butterfly's wings or the arch of the Sydney Harbour Bridge. Symmetry is everywhere in nature and design. In mathematics, special functions called even and odd functions capture this symmetry in precise, testable rules.

  • The algebraic definitions of even and odd functions
  • Why $f(-x) = f(x)$ corresponds to $y$-axis symmetry

2. Success Criteria

By the end, you should be able to:

  • The algebraic definitions of even and odd functions
  • The geometric meanings of each type of symmetry
  • That a function can be neither even nor odd

3. Key Terms

FunctionA relation where each input has exactly one output.
DomainThe set of all possible input values for a function.
RangeThe set of all possible output values for a function.
Inverse FunctionA function that reverses the effect of the original function.
QuadraticA polynomial of degree 2, in the form ax² + bx + c.
DiscriminantThe expression b² - 4ac that determines the nature of quadratic roots.

4. Activity: Build the Lesson Map

5. Short Answer Questions

1. Explain this lesson goal in your own words: "The algebraic definitions of even and odd functions". Use one specific example from the lesson.

Band 32 marks

2. Apply this idea to a new example: "The geometric meanings of each type of symmetry". Show your reasoning clearly.

Band 43 marks

3. Analyse why this idea matters for understanding Odd & Even Functions: "That a function can be neither even nor odd".

Band 54 marks

6. Extend: Apply the Idea

Band 5/65 marks

A student gives a memorised answer about Odd & Even Functions but does not use evidence or reasoning.

Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.

7. Multiple Choice

1. What is the best first step when answering a question about Odd & Even Functions?

A. Identify the key concept being tested

B. Write every fact from memory

C. Ignore the command word

D. Skip examples and evidence

2. Which answer would show stronger understanding of Odd & Even Functions?

A. An answer with accurate terms and reasoning

B. A copied definition only

C. A single-word response

D. An answer with no example

3. What should you do if a question asks you to explain?

A. Link the idea to a reason or cause

B. List unrelated facts

C. Only draw a diagram

D. Write the shortest possible answer

8. Success Criteria Proof

Finish with evidence that you can do each success criterion.

Success criterion 1

Prove that you can: The algebraic definitions of even and odd functions

Band 32 marks
Success criterion 2

Prove that you can: The geometric meanings of each type of symmetry

Band 43 marks
Success criterion 3

Prove that you can: That a function can be neither even nor odd

Band 54 marks
