When determining the domain of the radical function $f(x) = \sqrt{x - 2}$, which of the following mathematical conditions must the radicand satisfy to ensure the output is a real number?

A technical specialist is monitoring a quality control system modeled by the radical function $f(x) = \sqrt{x - 2}$, where $x$ represents the input pressure. To ensure the model is applied correctly, match each mathematical feature of this function with its correct value or description.

A technical specialist is preparing a maintenance manual for a system modeled by the radical function $f(x) = \sqrt{x - 2}$. To properly document the behavior of this model, arrange the following steps in the correct chronological order to determine the function's domain and the starting point of its graph.

A quality control specialist is plotting a performance model defined by the radical function $f(x) = \sqrt{x - 2}$. The specialist recalls that the graph of this function is a continuous curve that originates at the coordinate point (____, 0).

A financial analyst uses the mathematical model $f(x) = \sqrt{x - 2}$ to project the stability of an investment portfolio based on a risk index $x$. When analyzing this continuous curve to determine all possible outcomes, the range of the function establishes that the projected stability ($y$-values) will always be greater than or equal to 2.
