1. Key Ideas

Real problems do not arrive labelled "find the inverse" or "evaluate the composite." They demand that you choose the right tool, combine several ideas, and work step by step. This lesson brings together everything you have learned about functions, notation, domain, inverses, and composites into integrated, exam-style problems.

  • How to combine evaluation, domain, inverse, and composite skills
  • Why breaking a complex problem into smaller steps is essential

2. Success Criteria

By the end, you should be able to:

  • How to combine evaluation, domain, inverse, and composite skills
  • The connections between algebraic and graphical representations
  • Common exam question structures that mix multiple concepts

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.
