ofaFUNCTIONf(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中学生数学:高中...
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: I multiply the denominator up to the left-hand side of the equation: y(x − 5) = −2 I take the y through the parentheses: xy − 5y...
g(x)=4x+20. The inverse of a Function:Functions are relations containing two variables. We can perform arithmetic and algebraic operations with them and also develop their graph. One of the operations that we can perform with functions is to find their inverse; it consists of finding ...

注意inverse function是反函数的意思。若反函数存在，则直接函数必须是一一映射，既对每一个y值，有唯一的x值与之对应。具体到你的题目，y=2x^2-3, 若不规定x的范围，其自然定义域是R，既全体实数，但此时反函数不存在。 在规定了x<=0的前提下，其反函数为 y = -[(x+3)/2]^(1/2)....
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)...
The inverse trigonometric function is arcsin (also denoted as sin-1). The domain of arcsin (the range of valid inputs) is -1 ≤ x ≤ 1 . The range of arcsin (the range of possible outputs) is 0 ≤θ≤π. The opposite side's length is 2 cm for our example. The hypotenuse's le...
So the answer is: g(x)=(exp(x)-72)/68, where the domain of x is (-inf,inf) 注:"inf"指"无穷大" 4.1-4.3的都是让你判断单、满、双射或“无等价”关系的.只要知道定义,很容易判断的.So the answers are 4.1 injective(非满射是因为值域里的a9没有对应的映射) ...
