Question: How do i identify the parent function?
Explanation: when we think of the linear functions which make up a family of functions the parent function would be y = x.
Answer: Expand and simplify the function. For example expand the function y=(x+1)^2" to "y=x^2+2x+1.
Remove any transformations from the functions. This includes sign changes, added and multiplied constants and extra terms. For example, you can simplify "y=2*sin(x+2)" to "y=sin(x)" or "y=|3x+2|" to "y=|x|."
