To find the inverse function of y = f(x), switch the variables and solve for y.

Switch the variables.

Now, solve for y. First, separate the fraction.

Reduce .

Subtract 1 from the equation.

Take the reciprocal of the equation.

Therefore, the inverse function of f(x) is .

Use the same procedure for the second function.

Switch the variables.

Subtract 2 from the equation.

Reverse the sign of the equation.

Take the reciprocal of the equation.

Subtract 1 from the equation.
