Here we have the function f(x) = 2x+3, written as a flow diagram:The Inverse Function goes the other way:So the inverse of: 2x+3 is: (y−3)/2The inverse is usually shown by putting a little "-1" after the function name, like this:f-1(y)...

This equation does not describe xx as a function of yy because there are two solutions to this equation for every y>0y>0. The problem with trying to find an inverse function for f(x)=x2f(x)=x2 is that two inputs are sent to the same output for each output y>0y>0. The ...
解析 $$ y= \frac{3}{2}(x-11) $$ sove for x in ferms ofy So,$$ y= \frac{3}{2}(x-11) $$ →$$ \frac{2}{3}y=x-11 $$ $$ x= \frac{2}{3}y+11 $$ $$ h^{-1}(x)= \frac{2}{3}x+11 $$ 反馈 收藏
《Inverse ofa Functionf(x)=y》For a function y=f(x)to have an inverse function,f must be one-to-one.Then for each x in its domian there is exactly one y in its range;furthermore,to each y in the range,there corresponds exactly one x in the domain.The correspondence from the ...
I'll use this to find the domain and range of my inverse. Here's the algebra for finding that inverse, starting with the original function: y=−2x−5y=x−5−2 I multiply the denominator up to the left-hand side of the equation: y(x − 5) = −2 I take the y ...
The arccosine function is the inverse function of cos(x).arccos(x) = cos-1(x)For example, If the cosine of 60° is 0.5:cos(60°) = 0.5Then the arccos of 0.5 is 60°:arccos(0.5) = cos-1(0.5) = 60°Arccos tablexarccos(x) degreesradians -1 180° π -0.8660254 150° 5π/6...
The arctangent function is the inverse function of y = tan(x).arctan(y) = tan-1(y) = x+ kπFor everyk = {...,-2,-1,0,1,2,...}For example, If the tangent of 45° is 1:tan(45°) = 1Then the arctangent of 1 is 45°:...
