Question

What is the domain of the function y=^3 sqrt x-1

Answer 1

Answer: -infinity and positive infinity

Step-by-step explanation: It's either a on your test or two zero's that look twisted :)

Answer 2

Domain is all real numbers also known as
`(-\infty,\infty)` in interval notation.

`f(x)=\sqrt[3]{x-1}`?

Explanation:

If your function is
`f(x)=\sqrt[3]{x-1}` then the domain is all real numbers because you can cube root any real number.

If x is a real number, then x-1 is a real number.

So if you cube root (x-1) for any x then you still get a real number back.

Now if it was a square root, that is when we can run into some problems.
