The chirp rate, C, in chirps per minute, of the snowy tree cricket is given by C = f(T) = 4T − 160 where T is degrees Fahrenheit.

a. Find an appropriate domain of f in the context of the model assuming a maximum temperature of 134°F, the highest recorded at a weather station.5

b. Find the range of f on this domain.

Step 1

The given chirp rate is C = f(T) = 4T - 160 where T is degrees Fahrenheit.

Step 2

*Part(a):*

To find an appropriate domain of f in the context of the model assuming a maximum temperature of 134°F.

It is given that the maximum temperature is 134°F. Thus the maximum value of the domain is 134°F.

Now to find the minimum value, assume that the chirping rate is zero and find the temperature at that time. Since chirping rate goes down from zero is not logical.

Step 3

*Answer:*

The domain of the function assuming the given condition is [4...
