Notes
B2: for 4 correct values (B1 for 2 or 3 correct values)

Notes
M1: (dep on B1) ft from (a) for at least 5 points plotted correctly
A1: for a correct graph (clear intention to go through all the points and which must be curved at the bottom) Note: If a fully correct graph is shown, but an incomplete table is shown in (a), then award the marks for (a)
