How do you find the inverse of a function algebraically?

To find the inverse of a function algebraically, start by replacing the function notation ( f(x) ) with ( y ). Then, interchange the roles of ( x ) and ( y ) in the equation, which means you solve for ( y ) in terms of ( x ). Finally, express the new equation as ( f^{-1}(x) = y ). Verify that the composition of the function and its inverse yields the identity function, confirming they are true inverses.
