Hurry Please). The function f (x) models the value of goods that are imported into the United states, where x is the number of years since 1990. The function g (x) models the value of goods that are exported from the United states. If f (x) and g (x) continue to model the importing and exporting of goods, then sometime in 2041, which is 51 years after 1990, f (x) = g (x). Determine which function is exponential. Use the table of values to justify your choice.​
