See below

Step-by-step explanation:

( a ) The value 1200 in this content represents the starting value, or the number of bacteria that was present in the beginning.

( b ) 1.8 represents the growth factor, or by how much more the bacteria increases, in multiples of the quantity.

( c ) As you can tell 1000 has a similar function as 1200, it models the number of bacteria present in the beginning. The difference between the studies is that the second study is present with a starting value of 1000 yet a similar growth factor, and hence will always have a smaller number of bacteria after t hours.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
