The graph represents f(x) = .
On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is an open circle. The right end of each segment is a closed circle. The left-most segment goes from (negative 5, negative 1) to (negative 4, negative 1). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (1, 5) to (2, 5).
What is f(−2.2)?

To determine the value of f(-2.2), we need to find the segment on the graph that contains the point (-2.2, __). In this case, (-2.2, __) falls within the same segment as (-3, -2) because the segments are each 1 unit long and 1 unit higher.
So, f(-2.2) = -2 (the y-coordinate of the point where the segment with the point (-3, -2) lies).
Therefore, the answer is -2.
