The research of function with absolute value in Mathematics teaching

摘要

In order to study the application of functions with absolute value in mathematics teaching，concrete functions are used The horizontal and vertical research is carried out，and the two kinds of concrete functions are graphized by the two teaching ideas of flip transformation and absolute value removal. In this paper，two specific functions will be used to carry on the study of function image transformation，forming the idea of mathematics teaching. The results show that the two teaching ideas of flip transformation and absolute value removal can deal with the function image problem effectively.
