The amplitude and wavelength are measured in meters while frequency is measured in decibels.
<h2>
Units of measurement:</h2>
- Amplitude: It is the maximum displacement of the points of the wave from its mean position. Hence it is measured in meters.
- Frequency: It is measured in Hertz. A hertz is a number of waves passed from a single point per second.
- Wavelength: It is the distance between two consecutive crests or troughs. hence it is measured in meters.
- Wave speed: It is measured in m/s.
- Loudness: The loudness of the sound is measured in decibels.
Therefore, the amplitude and wavelength are measured in meters while frequency is measured in decibels.

Answer:
f(-9) = 184
Explanation:
f(x)=3x²+5x-14
f(-9)= 3(-9)² +5(-9)-14 Order of Operations : Exponents
= 3(81)+5(-9)-14
= 243+5(-9)-14
= 243-45-14
= 198-14
f(-9)= 184
Hope this helps :)
