If an inverse function undoes the work of the original function the original function's becomes the inverse function's domain?
The original function's RANGE becomes the inverse function's domain.
How do you find the inverse of an equation?
Generally, to find the inverse of an equation, replace every x with y and replace every y (otherwise written f(x) ) with an x. Then it's "good form" to get the equation into y= form. For an equation involving only two variables, the inverse can be found by swapping the x and y variables. Then, solve for y. If the equation does not define y as a function of x, the function f does not have an inverse. In order to start talking about an inverse, be sure first, that the given equation defines y as a function of x. Not every graph in the rectangular system is the graph of a function. For example, if you have an equation: x^2/4 + y^2/9 = 1 it's wrong to say the inverse will be: y^2/4 + x^2/9 = 1. Both of the above equations are ellipses. The original equation is an ellipse with the major axis (the long axis) on the y-axis, while the other has the major axis on the x-axis. Both of them do not represent a function, because if you solve for y, you'll see that two values of y can be obtained for a given x. Please note that if you are talking about functions, then not every function has an inverse, as a function must be one-to-one in order to have an inverse. A function must pass the "horizontal line test", which states that the graph of a function must never intersect with a horizontal line more than once, anywhere on it's domain. Inverse functions have some special properties: 1) The graph of an inverse function is the reflection of the original function reflected across the line y = x. 2) A function and it's inverse cancel each other out through functional composition.

What is the relationships between inverse functions?
The inverse of the inverse is the original function, so that the product of the two functions is equivalent to the identity function on the appropriate domain. The domain of a function is the range of the inverse function. The range of a function is the domain of the inverse function.
Is it possible for a fourth degree function to have an inverse that is a function?
In order for a fourth degree function to have an inverse function, its domain must be restricted. Otherwise the inverse function will not pass the vertical-line test.Ex.f(x) = x^4 (x>0), the original functionf-1(x) = x ^ (1/4), the inverse

What is the inverse for the equation 7x plus 3?
To find the inverse of a function, simply switch the variables x and y. So for the function y=7x+3, the inverse would be x=7y+3, or y=(x-3)/7.

Is the inverse a function?
a relation that is the inverse of the original function. So the variables ( x and y) are swapped. xcoordinatesbecomes ycoordinatesand vice versa.f(x) = 2x +5inverse f(x) = (x - 5)/2
How do you illustrate an inverse function?
Given a function, one can "switch" the variables x and y and then solve for y afterwards to determine the inverse function.
What is the relationships between inverse functions?
The inverse of the inverse is the original function, so that the product of the two functions is equivalent to the identity function on the appropriate domain. The domain of a function is the range of the inverse function. The range of a function is the domain of the inverse function.
What is an inverse of a function?
The opposite of another function - if you apply a function and then its inverse, you should get the original number back. For example, the inverse of squaring a positive number is taking the square root.
Why a constant function doesn't have an inverse function?
When graphing functions, an inverse function will be symmetric to the original function about the line y = x. Since a constant function is simply a straight, horizontal line, its inverse would be a straight, vertical line. However, a vertical line is not a function. Therefore, constant functions do not have inverse functions. Another way of figuring this question can be achieved using the horizontal line test. Look at your original function on a graph. If any horizontal line intersects the graph of the original function more than once, the original function does not have an inverse. The constant function is a horizontal line. Under the assumptions of the horizontal line test, a horizontal line infinitely will cross the original function. Thus, the constant function does not have an inverse function.
What is inverse of a function?
Simply stated, the inverse of a function is a function where the variables are reversed. If you have a function f(x) = y, the inverse is denoted as f-1(y) = x. Examples: y=x+3 Inverse is x=y+3, or y=x-3 y=2x+5 Inverse is x=2y+5, or y=(x-5)/2
