4. (a) Complete the table of values for y = x3 – 3x + 1
(b) On the grid below, draw the graph of y = x3 – 3x + 1 for values of x from –2 to 2

5. Find the value of
Give your answer correct to 1 decimal place.

6. The cumulative frequency graph gives information about the number of minutes each of 60 people was in a shop.
(a) Find an estimate for the number of people who were in the shop for more than 40 minutes.
Stan has to use the graph to find an estimate for the lower quartile of the times.
Stan writes,
60 people were in the shop.
25% of 60 = 15
So the lower quartile of the times is 15 minutes.
(b) What mistake has Stan made?

She has 2500 kg of potatoes, correct to the nearest 10 kg.
Kelly is going to put the potatoes into sacks.
Each sack will contain 12.5kg of potatoes.
Kelly assumes that 12.5 kg is measured correct to the nearest 0.1 kg.
(a) Does Kelly definitely have enough potatoes to fill 200 sacks?
You must show how you get your answer.
Kelly’s assumption is wrong.
12.5kg is measured correct to the nearest 0.5kg.
(b) Explain how this could affect your decision in part (a).
