Question

A social media website had 700,000 followers in 2014. The number y of followers increases by 6% each year.

a. Write an exponential growth function that represents the number of followers t years after 2014.
b. How many people will be following the website in 2019. Round your answer to the nearest thousand.

Answer 1

a. y=700,000*(1+6%)^t

b. 2 years later which means t=2, hence, y=700,000*(1+6%)^2=786520
round to the nearest thousand: y=78700
