这个陈述也称为逆函数定理(inverse function theorem)。 示例:极坐标 作为上述内容的简单应用,考虑由极坐标(polar coordinates) 参(R,θ)参 数化的平面。 我们可以通过定义函数 和x(R,θ)=Rcos(θ)和y(R,θ)=Rsin(θ) 转到新的坐标系(笛卡尔坐标)。这使得给定任何点 (R,θ) 都可以找到相应的...
y=f(x+k) (如果k>0,表示f的图像向左移动k个单元,如果k<0,表示f的图像向右移动|k|个单元。) 7.4函数图像的伸缩和反射(Scaling and Reflecting a Graph of a Function) 伸缩函数y=f(x)是指往水平或垂直方向拉伸或者压缩这个函数。这是通过使用一个合适的常量c去乘以这个函数或者乘以这个自变量x来实现的。...
Zooming and Re-centeringTo zoom, use the zoom slider. To the left zooms in, to the right zooms out. When you let go of the slider it goes back to the middle so you can zoom more.You can click-and-drag to move the graph around....
Use Desmos to graph the function f(x)=3x+4+2f(x)=3x+4+2 then use reflection about the line y=xy=x to graph the inverse function y=f−1(x)y=f−1(x). Show Answer Example 2 An exponential function has domain (−∞,+∞)(−∞,+∞) and range (2,+∞)(2,+∞). What...

21.1. Graphical Representation of the Inverse Explain the idea of an inverse function and its graph in your own words. Hint 21.1. Reverse or Mirror Inverse 1) Use general function composition notation to express the statement, “The function g undoes what f does.” as an equation. How do ...
Green For each function i) Sketch the graph showing intersections with the axes and asymptotes ii) State the domain and range of the function iii) Find the inverse function iv)Sketch the graph of the inverse function9) f(x)=(2x+3)/(x-1)x-110) g(x)=(3x-1)/(x+2)x+211) f(x...
四、反函數(inverse function) 若有一函數 f 代表 X→Y,則其反函數 f⁻¹ 就是 Y→X,可以有反函數的函數稱為「可逆函數(invertible function)」,所有可逆函數必為雙射函數。 在下圖中,f(x) 與 f⁻¹(x) 互為反函數關係、g(x) 與 g⁻¹(x) 亦互為反函數關係。對於 f(x) 及 g⁻...
They are the removable, jump, and asymptotic discontinuities. (Asymptotic discontinuities are sometimes called "infinite"). What is a discontinuity in a function? A discontinuity is a point where the graph of a function breaks. More formally, it is a point where the function either is not ...
