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.

How do you find the inverse of the slope of the line?
Write the equation of the line in the standrad form: y = mx + c The slope of this line is m The inverse of the slope is then 1/m. Note, that for a line perpendicular to the first, you need the negative inverse, not just the inverse. And the negative inverse of m is -1/m.
How can you tell if a equation is inverse?
Graph that equation. If the graph pass the horizontal line test, it is an inverse equation (because the graph of an inverse function is just a symmetry graph with respect to the line y= x of a graph of a one-to-one function). If it is given f(x) and g(x) as the inverse of f(x), check if g(f(x)) = x and f(g(x)) = x. If you show that g(f(x)) = x and f(g(x)) = x, then g(x) is the inverse of f(x).
If a function uses variables other than x and y for its input and output variables you take the original equation and solve for the output variables to find the inverse true or false?
It is false.

Why the multipicative inverse of zero does not exist?
To find the multiplicative inverse, you would have to solve the equation 0 times x = 1. Since any number times 0 is zero, this equation has no solution.

What is the inverse function of the equation 3x minus 4 divided by 2?
So y = (3x - 4)/2. To find the find the inverse equation, y-1,(1) Rewrite the equation replacing all ys with xs and all xs with ys.x = (3y - 4)/2(2) Solve the new equation for yx = (3y - 4)/22x = 3y - 42x + 4 = 3y(2x + 4)/3 = yThis is your inverse equation!y-1 = (2x + 4)/3
How do you find the inverse of the slope of the line?
Write the equation of the line in the standrad form: y = mx + c The slope of this line is m The inverse of the slope is then 1/m. Note, that for a line perpendicular to the first, you need the negative inverse, not just the inverse. And the negative inverse of m is -1/m.
Why do you use an inverse operation?
Inverse operations are used to undo mathematical operations and isolate a variable. They help to solve equations and simplify expressions by moving operations to the opposite side of the equation. This allows us to find the value of the variable that makes the equation true.
Find the inverse variation equation if x equals 5 when y equals 9?
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
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 xy 7 inverse equation?
It is difficult to be certain. Limitations of the browser used by Answers.com means that we cannot see most symbols. Please resubmit your question spelling out the symbols as "plus", "minus", "equals". If the question is about xy = 7, then it is an equation of an inverse relationship. This is NOT the same as an inverse equation.
