y = x/(x - 3)
so y(x - 3) = x
xy - 3y = x
xy - x = 3y
x(y - 1) = 3y
x = 3y/(y - 1) for y ≠1
So, the inverse function is
f(y) = 3y/(y - 1) where y ≠1

If f of x equals x divided by x minus one then what is the inverse?
x=x-1/x
What is the inverse function of y equals 2x minus 4?
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.
Given the function y equals minus 3 divided by 4 x square plus 15 what is the value of y when x equal minus 3?

What is the inverse function of the equation y equals 4x plus 9 Divided by 2x minus 3?
y = (4x+9)/(2x+3)2xy+3y = 4x+93y-9 = 4x-2xy3y-9 = x(2-2y)x = (3y-9)/(2-2y)So, inverse function is 3x minus 9 divided by 2 minus 27.

What is the inverse of the function f(x) x 12?
What is the inverse of the function f(x) = x + 12?The inverse of adding 12 is subtracting 12, so the inverse function is g(x) = x -12.(There is a special method for finding the inverse of more complicated functions, but it isn't needed here.)
