Composite Inverse Functions (Inside-Out Method) | Algebra 2

In this lesson, we evaluate a composite inverse function step by step using the inside-out method. We are given two functions, g and h, defined by ordered pairs, and asked to evaluate: g⁻¹(h(g⁻¹(2))) This example is important because the final answer is undefined, which helps students understand when and why a function composition must stop. In this MathByTV lesson, you’ll learn: How to evaluate inverse functions from ordered pairs How to work inside out with function composition How to recognize when a function value is not defined Why are undefined results valid in Algebra 2 This calm, clear explanation is ideal for: Algebra 2 students Precalculus readiness Reviewing inverse functions Understanding domain restrictions MathByTV focuses on clear, step-by-step math instruction, enabling students to understand the process rather than memorize steps. #CompositeFunctions #InverseFunctions #Algebra2 #FunctionComposition #MathByTV #Undefined #InsideOut #HighSchoolMath
