2. Practice more and pay attention to the special values of each quadrant and critical point in the coordinate system.

In the function part of higher algebra, we have studied several different types of functions, such as exponential function, logarithmic function, power function, trigonometric function and so on. But comparing and summarizing, you will find that whatever kind of function we need to master is its expression, image shape, parity, increase and decrease and symmetry. Then you can make the above contents of these functions into a big table and compare them for easy understanding and memory. Pay attention to the combination of function expressions and figures when solving problems, and you will certainly get much better results.

Secondly, you should practice more, and the combination of numbers and types will play a very significant role!
