If the new curriculum standard is used, the most important thing for senior one students is compulsory one (function), especially after all the compulsory one 1-4 is finished, it is best to learn the function again, which determines the methods and skills of learning mathematics in senior two and the level of mathematics ability in senior three.

As for function, we should pay attention to its properties: domain, range, monotonicity, parity, periodicity and function image.

We should practice these functions repeatedly: linear function, quadratic function (the most important), exponential function, logarithmic function, power function and test function.
