A technician is monitoring a periodic electrical signal on an oscilloscope. Based on the technical specifications provided for the signal's graph, match each mathematical feature of the signal to its correct value or coordinate.

A telecommunications technician is monitoring a continuous signal on an oscilloscope. The technical documentation for the signal's graph describes it as a periodic wave that extends infinitely to the left and right along the horizontal axis, covering all possible time values. Based on this documentation, what is the domain of the signal's function?

A technician is trained to read system performance from a graph. Arrange the following steps in the correct order to determine the value of a function $f(x)$ for a specific input using its visual plot.

An electronics technician is analyzing a periodic wavy signal on a diagnostic monitor. If the graph of the signal contains the point $(-\frac{3}{2}\pi, 2)$, then the value of the function $f(-\frac{3}{2}\pi)$ is 2.
