23.7 A First Look at Power Functions: Toward More Functions
Point 3 of 5
23.7.3 Odd, Even, and Symmetry
Core idea
Even powers are mirror-symmetric like a bowl while odd powers are symmetric about the origin like a slide, and the exponent decides which.
Module goal. Abstract a family of power functions from y=x², recognize their shared pattern, and pave the way for exponentials, logarithms, and other new functions ahead.
