Question

Which of these is the parent function y=x-4 a.f(x)=c b.f(x)=x C.f(x)=x3 d.f(x)=x Please help.

Answer 1

As you may know a parent function is the simplest function of a family of functions that preserves the definition (or shape) of the entire family. In this case, if:

y = √(x - 4)

The parent function is:

f(x) = √(x)
