So you want to solve f(x) = 2.
Apply the inverse function to both sides:
.
But .
Therefore .
So the solution to is .
You know how to find the inverse of ? (No? This thread here might give you some clues ......)
I don't get how can we solve an equation by finding the inverse of that function. What has the inverse of that function got to do with solving the equation?
Function is:
f(x) = (x + 3) / (x -5)
Equation is:
(x+3) / (x-5) = 2
Please help ...
