What is liner parent function?

The linear parent function is the simplest form of a linear equation, typically expressed as ( f(x) = x ). It represents a straight line that passes through the origin (0,0) with a slope of 1, meaning for every unit increase in ( x ), ( f(x) ) also increases by 1. This function serves as a foundational model for understanding linear relationships and can be transformed by applying various operations like shifts and stretches.
