Solution
f(x) = x
first tranformation : It is mirror image of x about y - axis
==> f(x) = -x
second tranformation : It is moved 2 units to the left
==> f(x) = -(x +2) = (-2 - x)
third tranformation : It is moved 3 units downwards
==> f(x) = (-2 - x) - 3
==> final function is f(x) = -3 + (-2 - x)
2) f(x) = (x + 4)/(6x - 6)
let f(x) = y ==> y = f-1(x)
==> y = (x + 4)/(6x - 6)
==> y(6x - 6) = x +4
==> 6xy - 6y = x + 4
==> 6xy -x = 6y + 4
==> x(6y - 1) = (6y + 4)
==> x = (6y + 4)/(6y - 1)
==> f -1(y) = (6y + 4)/(6y - 1)
==> f -1(x) = (6x + 4)/(6x - 1)
==> f -1(x) = 2(3x + 2)/(6x - 1)
