| Abstract: | One of the hot topics in senior high school entrance ex- amination is the use of quadratic function to solve mathematical problems or practical problems,. These problems often need to use quadratic function to express the relationships among the variables, and find out the quadratic function analysis formula, which is the key to solving the problems. This paper mainly in- troduces the common methods of solving the quadratic function analysis formula. |
