In iyour solution of 12th class exercise 1.3 question 14 how the last to lines came .
To find inverse of a function,
For example in the question
f(x) = 4x / (3x + 4)
y = 4x / (3x + 4)
x = 4y / (4 - 3y)
So, this x is the inverse,
Thus, we write,
g(y) = 4y / (4 - 3y)
The correct answer should be B.
There is a mistake in the last two lines.
We will correct and it update it.
