4 One of the diagrams below shows the graph of \(y = \arccos x\)

Identify the graph of \(y = \arccos x\)

Tick (✓) one box. [1 mark]

Four graphs, each with a tick box: top-left increasing curve from (−1, 0) through (0, π/2); top-right increasing curve through O from x = −1 to x = 1; bottom-left decreasing curve from (0, π/2) through (1, 0); bottom-right decreasing curve through (0, π/2) to (1, 0)
