How would I find out if there is any value of x that would make the function f(x)=\[\sqrt[3]{x-2}+3\] undefined?

OpenStudy (anonymous):

Since you can take the Cube-Root of a negative number, i.e. \[\sqrt[3]{-8} = -2\]This function is defined everywhere. If it were a Square-Root, The function would be undefined for \[x < 2\] (Remember, the Square-Root of a negative number is undefined on the real axis)

so all real numbers is where x is undefined or just 2?

OpenStudy (anonymous):

The function is DEFINED everywhere. In other words, there are no values of x to make the function UN-defined. Those numbers I posted were just examples to illustrate the point.. Just to clarify, are there any real number values of x that will make \[\sqrt[3]{x}\] undefined??
