Designers at a shock absorber manufacturing company conducted a series of experiments that produced oscillations similar to the behavior of a sine wave for any type of road. Each experiment lasted 20 minutes: the first 9 minutes on a surface simulating a paved highway, and the remaining 11 minutes on a surface simulating a dirt road. For the shock absorbers to be approved in the experiment, the amplitudes of the oscillatory waves on each type of surface must be constant, and the amplitude of oscillation on the asphalt must be smaller than the amplitude on the dirt road. The type of graph that describes the oscillatory behavior of a shock absorber approved in this experiment is
