Question

What is the domain of the function f(x) 2/5 startroot x = ? all real numbers all real numbers less than 0 all real number less than or equal to 0 all real numbers greater than or equal to 0

Answer 1

Answer:

$\boxed{\sf all \ real \ numbers \ greater \ than \ or \ equal \ to \ 0}$

Step-by-step explanation:

The domain of a function is all possible values for x.

$\sf f(x)=\frac{2}{5} \sqrt{x}$

There are restrictions on x.

The square root of a number can be undefined if that number is less than 0.

The value of x is all real numbers greater than or equal to 0.
