The following two functions have a common input, year t:
I gives the projected amount of natural gas imports in quadrillion Btu, and E gives the projected natural gas exports in trillion Btu.
(a) Using function notation, show how to combine the two functions to create a third function, N, giving net trade of natural gas in year t.
(b) What does negative net trade indicate?
