Calculate the Average Rate of Change over the interval . g(x) = 0.05x ^ 2 - 1.3x + 22.8 \ 13,23\ for the function

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

Negative 5 1/12 + negative 4 1/4 + 6 3/4
