Math Problem Statement
Solution
To determine the range of the given graph, we need to identify the minimum and maximum values that can take.
-
The line graph shows two distinct points:
- The first point is open at , which means this point is not included in the range.
- The second point is closed at , meaning this point is included in the range.
-
Observing the direction of the line, it is sloping downward from left to right. The range is determined by the -values of the function, which decrease as increases.
Range:
- The highest -value is 2 (corresponding to the open point at , but since it is an open circle, 2 is not included in the range).
- The lowest -value is (corresponding to the closed point at ).
Thus, the range of the function, written as an inequality, is:
