Answer

Explanation:

Step1: Identify decreasing intervals

A decreasing interval is where the graph is going down. Looking at the graph, there are 2 such intervals.

Step2: Analyze similarity of decreasing intervals

Both decreasing intervals show the frequency is decreasing and both end at (0) Hz.

Step3: Analyze difference of decreasing intervals

One decreasing interval starts from a lower frequency (around (45) Hz) and the other starts from a higher frequency (around (120) Hz).

Answer:

  1. (2)
  2. All of the decreasing intervals indicate lengths of time when the frequency is decreasing. All of the decreasing intervals end at (0) Hz.
  3. C. The decreasing intervals start from different frequencies.
