Notes
B2: for −2, −1, 0, 1, 2 with no additions or repeats (B1 for 4 of −2, −1, 0, 1, 2 with no additions or repeats or for 6 values with no more than one incorrect value e.g. all of −2, −1, 0, 1, 2, 3 or for 5 values with one error)

Answer: Closed circle at \(x = 1\) and a line with an arrow to the left
B1
(1)
(3 marks)
Notes
B1: for a closed circle at \(x = 1\) and a line with an arrow of any length to the left
Allow ] for a closed circle
Allow a line without an arrow if it reaches to at least −3
