Below is data reflecting how many Instagram users there were 𝑡 years after Instagram debuted in 2010 (i.e. 𝑡=3 corresponds with the year 2013). (Data source: [link])
Using the exponential model…
E) What is the residual value associated with 𝑡=8 (year 2018)? Does the model overestimate or underestimate the actual number of Instagram users that year?
E) Legend states that when the number of Instagram users reaches 4000 million, the Instagram servers will explode. If this legend is true, what domain restriction should we put on the exponential model?
F) By what percent does the number of Instagram users increase each year?
