What is does parent function mean?

A parent function is the simplest form of a set of functions that share the same characteristics. It serves as a prototype from which more complex functions can be derived by applying transformations such as shifting, stretching, or reflecting. For example, the parent function of linear equations is ( f(x) = x ), while for quadratic equations, it is ( f(x) = x^2 ). Understanding parent functions helps in analyzing and graphing more complicated functions.
