Learn about the concept of the inverse of a function, with the concept being addressed in three ways: graphically, numerically, and algebraically. See that the inverse can be found by reversing the coordinates of points in a table, or switching x and y in the equation, or reflecting a function over the line y=x in a graph.
See the rest of my videos covering other Function Transformations concepts:    • ★ Function Transformations [Chapter 1...  

Corresponds to chapter 1, section 1.4 in McGraw-Hill's Pre-Calculus 12, but also fits with the Function Transformations unit from almost any other Pre-Calculus course or textbook.

My instructional approach emphasizes conceptual understanding of and connections between concepts and ideas, rather than just pure memorization.
