Learn inverse functions with a visual guide to reversing inputs and outputs, the horizontal line test, domain and range swaps, and reflections across y=x. Follow a worked linear inverse, verify both compositions, and see why x² needs a restricted domain before choosing the square-root branch. Save for algebra and AP Precalculus revision, then explore the matching NUM8ERS inverse functions guide.

Trig Functions And Their Inverses
Read about how I teach my high school students about inverse functions. Start by inverting coordinates to teach inverse functions. Notice the geometric connection with the inverse as the reflection over the line y=x. Multiple representations are explored: tables, graphs and equations. Blog post by Mathberry Lane
Teach Inverse Functions with this easy hand-drawn algebra infographic! Students learn how an inverse function undoes the original function using y = f⁻¹(x), with key rules like f(f⁻¹(x)) = x and f⁻¹(f(x)) = x. Includes steps for finding an inverse, swapping x and y, solving for y, graph reflection over y = x, examples, and real-life uses. Perfect for high school algebra, homeschool lessons, classroom anchor charts, functions practice, and quick revision. Save this pin to help students understand inverse functions, input-output relationships, and graphing with confidence. #InverseFunction #Functions #AlgebraBasics #MathForKids #MathEducation #HighSchoolMath #TeachingMath #Homeschooling #MathAnchorChart #StudyTips
Inverses Of Functions
Today, let's undo a function 💡 6 worked examples for finding inverse functions: swap x and y, solve in reverse order, keep domain restrictions, and verify with composition. Includes cube roots, square roots, and how to prove two functions are true inverses. Small steps, big progress! #MathFoundations #AlgebraSkills #ProblemSolving #InverseFunctions
Swap x and y, solve for the new output and use inverse notation. The input-output diagram shows how inverse functions undo each other.
