Which is the graph of g(x) = ⌈x + 3⌉? on a coordinate plane, a step graph has horizontal segments that are each 1 unit long. the left end of each segment is a closed circle. the right end of each segment is an open circle. the left-most segment goes from (negative 2, negative 5) to (negative 1, negative 5). each segment is 1 unit higher and 1 unit farther to the right than the previous segment. the right-most segment goes from (4, 1) to (5, 1). on a coordinate plane, a step graph has horizontal segments that are each 1 unit long. the left end of each segment is a closed circle. the right end of each segment is an open circle. the left-most segment goes from (negative 5, negative 2) to (negative 4, negative 2). each segment is 1 unit higher and 1 unit farther to the right than the previous segment. the right-most segment goes from (2, 5) to (3, 5). 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 3, negative 5) to (negative 2, negative 5). each segment is 1 unit higher and 1 unit farther to the right than the previous segment. the right-most segment goes from (4, 2) to (5, 2). 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).
