1 明确“主体”,突出重点1.1 函数与不等式(主体)代数以函数为主干,不等式与函数的结合是“热点”.(1)关于函数性质.单调性、奇偶性、周期性(常以三角函数为载体)、对称性及反函数等处处可考.常以具体函数,结合图象的几何直观展开,有时作适当抽象.
1 Defining the “subject” and highlighting the focus 1.1 Functions and inequalities (subjects) Algebra functions are the backbone, inequality and function combination is “hot spot”. (1) About the nature of the function. Monotonicity, parity, periodicity (usually in the triangle Functions as vectors, symmetries, and inverse functions can be examined everywhere. Often with specific functions, combined with intuitive visualization of the image geometry, sometimes appropriate abstraction.
