  1. The weekly factor say, x, of the insect population, can be found out by dividing \frac{8100}{900}
  2. They are asking the population when w = 0 or the population at the beginning. Prepare a table of values as shown below  

 The weekly factor you got by dividing as shown above is 9  This means that it is growing by a factor of 9. So at week 0 the population is 100.

      

 3.An exponential function is of the form y = ab^{x}. Just replace y with p, a = 100, b = 9, and x = w.
