23.7 A First Look at Power Functions: Toward More Functions
Point 5 of 5
23.7.5 Does the Base Change, or the Exponent?
Core idea
In a power function the base x changes while the exponent stays fixed; next you'll meet a new function where the base holds still and the exponent moves instead.
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.
