During a hearing test, an audiometer produces a pure tone with a frequency of 2,000 hertz (cycles/second). The given function represents the change in pressure, , in millipascals, relative to the normal air pressure in the room as a function of time, t, in seconds, after the pure tone is produced. What is the change in air pressure when the pure tone is produced?

If the table of the function contains exactly two potential turning points, one with an input value of –1, which statement best describes all possible values of m? m ≥ –12 –12 < m < 4 m ≤ 4 m ≥ 4 or m ≤ –12
