Functions A function expresses the relationship between variables. Values of these variables can be numbers or nonnumerical objects such as geometric figures,
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...
"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...
选项 B,y = -x 是减函数。选项 C,y = eˣ 是增函数,其反函数是 y = ln x,也是增函数。选项 D,y = log₂x 是增函数,但题干要求函数和反函数都是增函数,y = log₂x 的反函数是指数函数 y = 2ˣ,在定义域上是增函数。反馈 收藏 ...
设置InverseFunctions->False,Solve 不使用反函数:In[1]:=Out[1]= 这里,使用基于 Reduce 的方法,因为它不要求使用反函数:In[2]:=Out[2]=代数方程求解不需要用反函数:In[3]:=Out[3]= 参见 FindRoot 技术笔记 一元方程 历史 1991年引入 (2.0)
