Answer:

  about 198.1

Step-by-step explanation:

The instantaneous rate of change is given by the derivative:

  V'(t) = 100·e^(0.4t)(0.4)

  V'(t) = 40·e^(0.4t)

So V'(4) is ...

  V'(4) = 40·e^1.6 ≈ 198.1213

The instantaneous rate of change of views at day 4 is 198.1 views per day.

Answer:

Every day, the number of views grows by a factor of 1.53.
