What information can be inferred from Figure 1, the velocity-versus-time graph of a particle in simple harmonic motion?

From Figure 1, the velocity-versus-time graph of a particle in simple harmonic motion, we can infer the amplitude, period, and phase of the motion. The amplitude is the maximum velocity reached by the particle, the period is the time taken to complete one full cycle of motion, and the phase indicates the starting point of the motion within the cycle.
