Observation

The Chief Examiner stated that this question was also very popular among the candidates. According to the report, while majority of them could complete the table and draw the graph, majority of them could not read from the graph correctly. Even more of them could not calculate the required gradient by drawing the appropriate tangent to the curve. Candidates were expected to complete the table as follows;
