—then we can say that the action of g has extracted the argument x.Example 2. Solve for x:(x + 3)4 = 16.Solution. To do that, we must first extract the argument, x + 3. To extract the argument of any function, simply take its inverse. In this example, take the 4th root ...
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)...
Determine algebraically whether the function is one-to-one. Verify your answer graphically. If the function is one-to-one, find its inverse. f (x) = (x + 3)^2, x \geq -3 Determine algebraically whether the function is one-to-one. Verify your answ...

What is the inverse of f if f(x) = 3sqrt(x - 5)? What is the inverse f(x) = x^2 - 9 ? If f(x) = 3x - 5, what is the inverse of f(x)? What is the inverse function for f(x) = \sqrt{x - 4} - 3 for x \geq 4?
Since any output y=x3+4y=x3+4, we can solve this equation for xx to find that the input is x=3√y−4x=y−43. This equation defines xx as a function of yy. Denoting this function as f−1f−1, and writing x=f−1(y)=3√y−4x=f−1(y)=y−43, we see that ...
There is an inverse if the function is one-to-one or restrictions imposed to give this state of affairs. However, the function y = sin x gives many values of x for the same value of y. To obtain an inverse we have to restrict the domain of the function to −π/2 to +π/2. ...
If the function f(x) = x³ has an inverse function g(x), then g(8)=? A. 2 B. 3 C. 4 D. 5 相关知识点: 试题来源: 解析 A。因为 f(x) = x³,其反函数 g(x) = ∛x。当 f(x)=8 时,x = 2,所以 g(8)=2。反馈 收藏 ...
