Answer:
43.50 or 43.5
Step-by-step explanation:
We suspect the domain is values of x greater than 0 but less than about 100. At about x=70, the temperature matches that of the surface of the sun. Some experimental processes may produce higher temperatures, but a practical limit is certain to be x less than 4000, at which point the temperature exceeds the core temperature of the sun.
I think it's all real numbers . Not sure
-8 and -7, I used guess and check
.558 is rounded to the nearest thousandth
