This slideshow begins with a real-life application of composite functions - shopping with coupons! Students are then led to use composite functions algebraically and taught about inverse functions as well. Teacher examples and student practice problems are included. Though the problems begin as basic, they progress in difficulty and are designed for an upper-level math class such as Pre-Calculus or IB Math.
