Easy -1.8 This is a 1-mark question testing basic understanding of when the trapezium rule overestimates (concave up curves). It requires only visual recognition of curve concavity with no calculation, making it significantly easier than average A-level questions.
The trapezium rule is used to estimate the area of the shaded region in each of the graphs below.
Identify the graph for which the trapezium rule produces an overestimate.
Tick (\(\checkmark\)) one box.
