The table shows the number of subscribers $S (m)$ to a new online service, in thousands, $m$ months after its launch. The relationship is exponential. Which of the following functions best models the number of subscribers, and what is the approximate monthly percentage increase in subscribers?

m	S(m)
0	50
3	62.9856
6	79.3437

$S (m) = 50 (1.08)^{m}$ ; 8% increase

$S (m) = 50 (1.04)^{m}$ ; 4% increase

$S (m) = 50 (0.92)^{m}$ ; 8% decrease

$S (m) = 50 (1.08)^{m}$ ; 4% increase
