Question

Domain of y=
`\sqrt[3]{x}`

Answer 1

`- \infty , \infty`

What is a domain of an expression?

A domain of a expression is all real numbers except where the expression is undefined.

In the case of y=
`\sqrt[3]{x}`, there is no real number which makes the expression undefined.

Therefore, the domain is:

`- \infty , \infty`
