Which is a correct description of the graph below?
The graph shows a sine wave with a minimum value of negative 1 and a maximum value of 1. The wave completes 1 cycle in an interval from 0 to 2 pi. The wave passes through (0, 0), slopes down and hits a minimum value of negative 1 at pi over 2, has a value of 0 again at pi, hits a maximum value of 1 at 3 pi over 2 and has a value of 0 again at 2 pi.

y = −sin(x).
Reason: amplitude 1, period 2π, no vertical shift, and the graph is the sine reflected across the x‑axis. It passes through (0,0) with negative slope, has a minimum −1 at π/2, 0 at π, maximum 1 at 3π/2, and 0 at 2π, which matches −sin x.
