Domain Validation for Industrial Modeling Software

A quality control analyst at a manufacturing plant is updating the technical specifications for a stress-testing tool that utilizes the function f(x)=2x2+33f(x) = \sqrt[3]{2x^2 + 3} to predict material fatigue. To ensure the software's input validation logic is correct, the analyst must document the allowed range of input values. State the domain of this function in interval notation and explain the specific rule regarding the radical's index that allows for this domain.
