2
3
x + 14 to model the relationship. what does 14 mean?
a) the temperature only adds 14 to the damage index.
b) if there is no damage index then the ambient temperature is 14.
c) if the damage index is 0, then the ambient temperature would be 0.
d) if the ambient temperature is 0 then the damage index would be 14.
