The graph represents y = ⌈x⌉ + 1. 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 3) to (negative 4, negative 3. each segment is 1 unit higher and 1 unit farther to the right than the previous segment. the right-most segment goes from (3, 5) to (4, 5). what is f(–2.75)? –5 –4 –2 –1
