To find the inverse function ( f^{-1}(x) ) for the function ( f(x) = 3x - 1 ), we start by setting ( y = f(x) ), which gives us ( y = 3x - 1 ). We then solve for ( x ) in terms of ( y ):

  1. Add 1 to both sides: ( y + 1 = 3x ).
  2. Divide by 3: ( x = \frac{y + 1}{3} ).

Thus, the inverse function is ( f^{-1}(x) = \frac{x + 1}{3} ).
