During the winter, if the low temperature outside is x°C , the daily cost to heat a building can be determined using the function f(x)=5(1.3)⁻ˣ. Find and interpret the given function values and determine an appropriate domain for the function. Round all function values to the nearest hundredth. f(-3)=□ , meaning when the low temperature outside is □°C , it would cost $ □ to heat the building. This interpretation in the context of the problem.
