Question

1. Provide an exponential function representing Anita's social media shares.

Anita

Anita shared her photo with 42 followers. Each of them shared it with 2 friends, doubling the number of viewers each day.

Day    Viewers
0            42
1            84
2          168

Answer 1

Number of viewers = N0(2)^t; where N0 is the initial followers = 42 and t is the number of days.
Therefore, the required equation is N = 42(2)^t
