which situation could be represented by an exponential function select each correct answer

Answer:The first and third options are the examples of exponential functions.Step-by-step explanation:When a quantity is compounded after a certain interval of time at a certain rate, then we can assume that the situation can be represented by an exponential function.In the first option:  An event organizer finds each year's attendance for the past five years is about [tex]\frac{4}{5}[/tex] of previous year's attendance. So, here the total attendance is compounding every year by a factor [tex]\frac{4}{5}[/tex] of previous year's attendance. Again, in the third case: The total population is increasing by about 7.5% each year. Hence, the population is compounded every year by 7.5% of the previous year's population. Therefore, the first and third options are examples of exponential functions. (Answer)
