The importance of functions in high school mathematics is like building a building and laying a foundation, and many children do not learn functions well in the first year of high school, resulting in a very difficult time to learn the later knowledge. In the mathematics of the college entrance examination, functions not only have many points to be tested separately, but can also be combined with any subsequent chapters, especially the function range icon problem and the properties of functions.

One of the difficult and often tested in the college entrance examination is the use of functional properties (two test methods, one is to use functional properties to solve inequalities, compare magnitudes or constancy to find parameters, which mainly refers to the parity of functions, which may change into symmetry and monotonicity combination; Another difficulty of the function is the zero point problem of the function, that is, the number of zeros is judged by the combination of numbers and shapes, the number of known zeros is the parameter range, the zero point of the composite function, and the use of the zero-point property to find the parameter range or evaluation.

The best way to learn is to review the old and learn the new, and not forget to grasp the previous knowledge points after learning, and then review them to form long-term memory, so that it is not easy to forget. The question types, knowledge points, and classic example questions that will be tested in the following functional topics are listed one by one, whether it is a freshman study or a high school.

Second, the third year of high school is very practical for review, and winning this special topic mathematics will definitely improve to a new level. Children who have studied Mr. Wang's information will know that each knowledge point has a summary, question type, problem-solving skills and problem-solving methods, which is what every child who needs to improve his grades needs.
