1, starting from the basics: first understand the definition of function, such as what it is, what its function is, and its relationship with other mathematical concepts. Learning through examples: try to understand the properties of functions through examples, such as monotonicity and the concept of derivatives. Practice: Do more questions and try to solve them by yourself. If you don't understand, you can ask your teacher or classmates for help.
2. Combined with practical application: Try to apply the knowledge of function to real life, such as economy, physics, engineering and other fields. Perseverance: Function is an abstract mathematics subject, which needs patience and persistence to learn well.

1. function is a mathematical concept, which was first translated by China mathematician Li in his book Algebra. He translated this way because "any variable in this variable is a function of that variable", that is, a function means that one quantity changes with another quantity, or that one quantity contains another quantity.
2. The modern definition of a function is: for a given number set A, assuming that the elements in it are X, there is a corresponding rule F, marked as f(x), so that each element X in A can be mapped to an element Y in another number set B through F. At this time, the equivalent relationship between element X and its corresponding element Y can be expressed as y=f(x).
3. Definition of function: A function is a special mapping, which defines the mapping relationship between two sets. A function consists of a defined field and a corresponding rule. The domain is the range of independent variables that make the function meaningful, and the corresponding rule is the law to establish the relationship between independent variables and dependent variables.
4. Representation of functions: There are many ways to represent functions, including analytical method, tabular method and graphical method. Analytic method uses mathematical expressions to express the relationship between functions, tabular method uses tabular form to express the relationship between functions, and graphic method uses images to express the relationship between functions.
5. Properties of functions: The properties of functions include parity, monotonicity and periodicity. These properties describe the law and characteristics of the change of function value when the independent variable changes. Function operation: Function operation includes basic operations such as addition, subtraction, multiplication and division of functions, as well as complex operations such as composition and inverse function of functions.
