Math Problem Statement
Solution
The image shows a graph of a function on a coordinate plane. The graph is a straight line that starts from an approximate point of and moves downward to a point around . Since the instructions indicate that the graph continues infinitely in both directions if no endpoints are visible, we assume the line extends forever to the left and right.
Finding the Domain
The domain of a function is the set of all possible -values for which the function is defined. Since the line extends infinitely in both directions horizontally, the -values also cover all real numbers.
Therefore, the domain in interval notation is:

Tip:
When analyzing graphs, always check for visible endpoints or arrows that indicate the direction of continuation to determine the domain and range accurately.
