二. 学会求函数的值域或复合函数(composite function)的值域 对于one to one函数,直接带入定义域的两端点值即可得最大值和最小值 对于many to one函数,需要确定是否有极大值点和极小值点,并通过带入两端点值及极大值或极小值来确定值域 三.反函数(inverse function) 反函数的本质是横坐标和纵坐标互换,即x...
Functions A function expresses the relationship between variables. Values of these variables can be numbers or nonnumerical objects such as geometric figures,
"Let f and g be two functions such that f(g(x))=x and g(f(x))=x.The function g is called an inverse function of the function, f and vice versa".Since f(g(x))=x and g(f(x))=x, the functions f(x)= 1(x+1) and g(x)= (1-x)x are inverse functions of each othe...
