Introduction to Functions
- A function is a rule that assigns to every input value exactly one output value

- Domain is the set of all possible input values (x-values)
2
Methods of Representing Functions
- Analytical representation uses mathematical formulas or equations
- Tabular representation shows input-output pairs in table format
- Graphical representation plots points on coordinate plane
3
Even and Odd Functions
- Even functions satisfy f(x) = f(-x) for all x in domain
- Odd functions satisfy f(x) = -f(-x) for all x in domain
- Even functions are symmetric about y-axis
4
Inverse Functions
- Inverse function exists only when original function is one-to-one
- If y = f(x), then inverse is x = f⁻¹(y) or y = f⁻¹(x)
- Domain of f becomes range of f⁻¹ and vice versa
