Q. Fidel has a rare coin worth $550. Each decade, the coin's value increases by 10%.Which kind of function best models the relationship between time and the coin's value?Choose 1 answer:(A) Linear(B) Exponential
Identify Type Increase: Identify the type of increase in the coin's value.The coin's value increases by 10% each decade, which means the increase is a percentage of the current value. This is characteristic of exponential growth, not a constant addition.
Determine Function Type: Determine the type of function that models exponential growth.Since the value increases by a percentage (multiplicative change) rather than a fixed amount (additive change), the function that models this situation is an exponential function.
Choose Correct Answer: Choose the correct answer based on the type of function identified.The correct answer is (B) Exponential, as the coin's value increases by a percentage each decade.
