In a professional technical training session, an instructor asks you to identify the components of a machine's performance graph. Match each mathematical term with the correct observation needed to find it on the graph.

A quality control technician is examining a graph that monitors the pressure levels in a hydraulic press throughout a work shift. According to the standard procedure for reading graphs, to identify the range of the pressure levels recorded, which visual characteristic of the graph must be observed?

A data analyst is reviewing a performance graph in a technical report. According to the standard procedure for graph interpretation, the analyst should identify the range of the function by observing the horizontal spread of the curve along the $x$-axis.

Interpreting System Performance Graphs

When reviewing a machine's performance graph in a quality control report, an analyst needs to determine the horizontal spread of the graphed curve on the $x$-axis. By identifying this horizontal spread, the analyst is finding the ____ of the function.
