Question

The following data gives the cumulative number of participants eliminated in a tennis tournament by the end of each round.Which of the following represents the best relationship between the round and the the number of participants remaining in the tournament?

Round	Total Number of Participants Eliminated
$1$	$256$
$2$	$384$
$3$	$448$
$4$	$480$
$5$	$496$

• A. Exponential growth
• B. Exponential decay
• C. Linear growth
• D. Linear decay

Answer 1

The correct option is B Exponential decay

Since the total number of participants eliminated is increasing.

So, Exponential decay occurs in the same way when the growth rate is negative.
