Topics in Function
1
Definition and Basic Concepts of Functions
- A function is a unique relation between elements of two non-empty sets where each element of the first set has exactly one image in the second set
- For a relation to be a function, every element in the domain must have exactly one corresponding element in the codomain
- Functions are denoted by letters like f, g, h, and written as f: A → B
2
Types of Functions - Detailed Analysis
- One-One Function: Different inputs give different outputs (f(a₁) ≠ f(a₂) when a₁ ≠ a₂)
- Many-One Function: Different inputs can give the same output (f(a₁) = f(a₂) when a₁ ≠ a₂)
- Constant Function: All inputs give the same output (f(x) = c for all x in domain)
3
Equal Functions and Function Comparison
- Two functions are equal if they have the same domain and same functional values for every element
- Domain equality is necessary but not sufficient for function equality
- Equal functions must satisfy: f = g if Domain(f) = Domain(g) and f(x) = g(x) for all x in domain
4
Real Functions and Function Evaluation
- Real functions have domain and/or codomain as subsets of real numbers
- Function evaluation involves substituting values and simplifying expressions
- Domain restrictions occur when denominators become zero or expressions under square roots become negative
