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)?
