Types of Functions:
# Example of a Python function def square(x): return x * x # Calling the function result = square(5) print(result) # Output: 25
Key Concepts for Revision:
1. Domain and Range: The domain of a function represents the set of possible input values, while the range represents the set of possible output values.
2. Function Composition: Understand how to combine multiple functions to create a composite function.
3. Inverse Function Properties: Learn the properties and conditions for the existence of inverse functions.
4. Graphical Representation: Gain familiarity with graphing functions and interpreting their graphs.
1. Practice a variety of problems from your textbook and previous question papers to reinforce your understanding of functions.
2. Focus on understanding the concepts and the logic behind them rather than memorizing formulas.
3. Create a summary sheet with important formulas and properties to review before the exam.
4. Utilize online resources, video tutorials, and interactive quizzes to enhance your learning experience.
