Function concept itself is relatively abstract, its development has gone through a long process, if students can fully understand the concept in a short time is impractical, for the characteristics of this knowledge project and students’ cognitive abilities, The teacher is required to summarize the previous teaching methods, the use of new and effective teaching methods to improve the effectiveness of classroom teaching function.First, the function of learning challenging First, the concept of function itself is a relatively abstract concept, which The development of a concept has been going on for centuries, and its development and progress have progressed towards the direction of precision and abstraction. These characteristics of the function itself make it a very challenging one
