Question

Witch function has the same domain as y=2rootx

Answer 1

Answer: f(x) = √x  -  2

Step-by-step explanation:

Given the function: y = 2 √x

We are asked for the function that has the same domain as the given function

First, the domain for the given function is { x | x ≥ 0 }

So, any function that has a domain of x that is equal to or greater than 0.

Some examples include:

1. f(x) = √x  -  2
2. f(x) = 5 √x
