Question

b. explain the meaning of $f(0) = 0$.
c. write a statement about function $f$ that represents the fact that there were 28,800 followers 110 days after the set up of the account.
d. explain the meaning of $t$ in the equation $f(t) = 100,000$.

Explanation:

Part b

Assuming \( F(t) \) represents the number of followers \( t \) days after the account setup, \( F(0) = 0 \) means at \( t = 0 \) (the moment the account was set up), the number of followers was 0.

The function \( F(t) \) gives the number of followers \( t \) days after account setup. So when \( t = 110 \) (110 days after setup), \( F(110) \) should equal 28,800 (the number of followers).

In the equation \( F(t)=100000 \), \( F(t) \) is the number of followers \( t \) days after account setup. So \( t \) represents the number of days after the account was set up when the number of followers reaches 100,000.

Answer:

At the time the account was set up (0 days after setup), the number of followers was 0.
