The provided line graph illustrates the amount of athletes attending four distinct sports, namely badminton, basketball, tennis, and rugby, in a region from 1985 to 2005, recorded every five years. Overall, rugby and tennis witnessed noticeable downward and upward trajectories correspondingly, whereas the two former only saw minor fluctuations.
In 1985, rugby commenced predominantly at nearly 250 people, however, from 1985 onward, this figure saw a n exponential plummet, dropping by well over two-thirds of its original value to merely 50 athletes in 2005, thus becoming the least prevalent figure among all. Tennis, on the other hand, started off with approximately 150 people in 1985, before rising, moderately, yet continuously, over the next 30 years to reach its peak in 2005 with about 220 individuals, surpassing rugby to become the foremost figure from 2000.
Regarding the remainder, basketball and badminton figures, the former, once accounted for roughly 80 athletes in 1985, remained relatively stabilized over the studied period with minimal fluctuations. Badminton also did not undergo any substantial variations. Commencing at about 60 people, this figure dipped slightly to well under 50 five years later, before eventually staying unchanged to 2005, with its counterpart surpassing rugby’s by a tiny difference.
