The explanation is INCORRECT.
A "parent function" is a basic function that serves as a fundamental building block for a particular "function family," and it represents the simplest form of that family, not the most complicated. Other functions in the family can be derived from the parent function through transformations, such as shifts, stretches, or reflections. For example, the parent function for the cubic function family is \( f(x) = x^3 \).
Here’s the corrected paragraph:
A "parent function" is a function that has a graph that serves as the fundamental example for a "function family" and is the simplest form of that family. Some, but not all, of the functions in the "function family" can be derived algebraically from the "parent function" by multiplying by a constant, and/or by adding or subtracting terms. For example, \( f(x) = x^3 \) is the parent function of the cubic "function family."
