Reading the Range of a Function from its Graph
To find the range of a function from its graph, identify all the values of that correspond to a point on the graph. Visually follow a given -value left or right horizontally; if this horizontal path intersects the graph of the function, then that specific -value is mathematically included in the range.

A quality control technician is using a graph to track the temperature of a machine over an eight-hour shift. According to the visual method for determining the range of a function from its graph, which action confirms that a specific temperature value is included in the range?
A network administrator is reviewing a graph that shows the latency (in milliseconds) of a server over a 24-hour period. To find the range of latency values, the administrator must determine which millisecond levels were recorded by the system. Arrange the following steps in the correct order to visually confirm if a specific latency value is part of the function's range.
