Let
x-------> the number of hours
y------> the temperature in degrees Fahrenheit
we know that
For 

For 

The domain of the function is the interval----------> ![[0,30]](https://tex.z-dn.net/?f=%5B0%2C30%5D)

The range of the function is the interval----------> ![[-10,30]](https://tex.z-dn.net/?f=%5B-10%2C30%5D)

therefore
<u>the answer is</u>
The domain is all real numbers 0 through 30
I believe it’s 30,180,000
First do 4% -> 0.04x15=0.6
0.6+100=100.6x300,000
But then again I’m not too sure so double check
