Exploring Odd and Even Functions

This video tutorial introduces even and odd functions, explaining how to determine them using algebraic and graphical methods. Even functions have symmetry across the y-axis, while odd functions have rotational symmetry about the origin. The video provides examples using x squared and x cubed to illustrate these concepts, demonstrating algebraic proofs for each. The tutorial concludes with a brief mention of further examples available in subsequent videos.
