Answer:


-\infty<x<\infty

Explanation:

We have been given a function . We are asked to find the domain of our given function.


y=\sqrt[3]{x-1}

We know that domain of a function is all values of x for which our function is defined.

Upon looking at our given function, we can see that our given function is a cube root function. We know that a cube root function is defined for all value of x as it is possible for three negatives to equal a negative.

Therefore, the domain of our given function is all real value of x that is
(-\infty,\infty) and option A is the correct choice.
