During winter, if the low temperature outside is X °C the daily cost to heat a building can be determined by the function f (x) = 10 (1.3)^-x. Find and interpret the given function values and determine an appropriate domain for the function.
Round all functions to the nearest hundredth.
f(-8)= , meaning when the low temperature outside is °C, it would cost $ to heat the building. This interpretation [Does/Does Not] Make sense.
f(9)= , meaning when the low temperature outside is °C, it would cost $ to heat the building. This interpretation [Does/Does Not] Make sense.
f(9.5)= , meaning when the low temperature outside is °C, it would cost $ to heat the building. This interpretation [Does/Does Not] Make sense.
Based on the observations above, it is clear that an appropriate domain for the function is [All Real Numbers/Non-Negative Numbers/Real Numbers In A≤X≤B/Integers/Whole Numbers/ Positive Integers/ Integers In A≤X≤B]
