Calculus 1 — 2.5: Even and Odd Functions

Can you detect a function's symmetry without ever graphing it? In this video, you'll learn the simple algebraic test that reveals whether any function is even, odd, or neither—just substitute -x and watch what happens. We'll build visual intuition for y-axis symmetry (even functions) and origin symmetry (odd functions), then master the step-by-step testing procedure with clear worked examples. Key concepts covered: • Even functions: f(-x) = f(x) creates mirror symmetry across the y-axis • Odd functions: f(-x) = -f(x) creates 180° rotational symmetry around the origin • The mechanical test: substitute -x, simplify, and compare to the original • How to identify "neither" cases when terms behave differently • Pattern recognition tips using even and odd powers ━━━━━━━━━━━━━━━━━━━━━━━━ SOURCE MATERIALS The source materials for this video are from    • Calculus 1 Lecture 0.2:  Introduction to F...
