Question 12
A function can sometimes reflect on itself, i.e. if y = f(x), then x = f(y). Both of them retain the same structure and form. Which of the following functions has this property?
Solution
Putting y as x and x as y in given options, only options B satisfies the function property as follows.
x = $$\frac{2y+3}{3y-2}$$
or 3xy - 2x = 2y+3
or y(3x-2) = 2x+3
or $$y = \frac{2x+3}{3x-2}$$
