xy - y = 2x + 1
xy - 2x = y + 1
x(y - 2) = y + 1
so x = (y + 1)/(y - 2) assuming y�
2.
So the inverse function is f-1(x) = (x + 1)/(x - 2)
To find the inverse of a function, you replace x with y and y with x. Here, y=2x-4 would become x=2y-4. Now, we solve for y. 2y=x+4. y=(x/2)+4, and that is the inverse equation.
change it to an improper fraction and then divide it
To find the inverse, replace y with x, and x with y. So, the inverse of the equation is: x = 4yWhich is equal to:y = x/4
If f(x) = 4x + 12, to find the inverse, reverse the actions of the elements of the function in "reverse" order. The last thing done is "+ 12", so reverse that first by "- 12" The previous thing done was "× 4n, so reverse that by "÷ 4", but note that the divide takes precedence over subtract, so the previous step needs to be in brackets. Thus if the inverse of f(x) is g(x), g(x) = (x - 12) ÷ 4
The inverse of the logarithm of a number is ten to the number, meaning that the number is the exponent. In this case, 10^-3.1 equals approximately .0007943.
To find the inverse of a function, you replace x with y and y with x. Here, y=2x-4 would become x=2y-4. Now, we solve for y. 2y=x+4. y=(x/2)+4, and that is the inverse equation.

The inverse of a logarithmic function is an exponential function. So to find the "inverse" of the log function, you use the universal power key, unless you're finding the inverse of a natural log, then you use the e^x key.
To find the inverse simply switch the x's with the y's so... inverse of y=x is x=y
Divide 1 by the number. The multiplicative inverse of 7 is 1/7, for example.
Check out the acos function.
To find the inverse, replace y with x, and x with y. So, the inverse of the equation is: x = 4yWhich is equal to:y = x/4
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.
The only trig functions i can think of with horizontal assymptotes are the inverse trig functions. and they go assymptotic for everytime the non-inverse function is equal to zero.
The inverse of a function can be found by switching the independent variable (typically the "x") and the dependent variable (typically the "y") and solving for the "new y". You can also create a t-chart for the original function, switch the x and the y, and graph the new relation.You will note that a function and its inverse are symmetrical around the line "y = x".Sometimes the inverse of a function is not actually a function; since it doesn't pass the "vertical line test"; in this case, you have to restrict the new function by "erasing" some of it to make it a function.
If f(x) = 4x + 12, to find the inverse, reverse the actions of the elements of the function in "reverse" order. The last thing done is "+ 12", so reverse that first by "- 12" The previous thing done was "× 4n, so reverse that by "÷ 4", but note that the divide takes precedence over subtract, so the previous step needs to be in brackets. Thus if the inverse of f(x) is g(x), g(x) = (x - 12) ÷ 4
If its a fraction then we can change the numerators and denominators upside down .This is in case of fraction.
