Introduction In Common Core Algebra 2, the concept of inverse functions is a critical bridge between algebraic manipulation, graphical analysis, and real-world application. Students learn that functions map inputs to outputs, while inverse functions "undo" that mapping, taking outputs back to original inputs.

Find the inverse of ( k(x) = \sqrt{x - 2} ) and state its domain and range.

Find the inverse of ( h(x) = 4x + 7 ).
