Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number

Step-by-step explanation:

The base of the exponential factor in a growth formula is the growth factor. Here, that is 1.30. It represents the multiplier of the number of spores each week.

Putting 4 into the formula, we find ...

  f(4) = 345×1.30^4 ≈ 985 . . . . mold spores after 4 weeks

56
