Consider this function for cell duplication. The cells duplicate every minute.

f(x) = 75(2)^x

• The 75 is the initial number of cells, and the 2 indicates that the number of cells doubles every minute.

• The 75 is the initial number of cells, and the 2 indicates that the number of cells increases by 2 every minute.

• The 75 is the number of cells at 1 minute, and the 2 indicates that the number of cells doubles every minute

• The 75 is the number of cells at 1 minute, and the 2 indicates that the number of cells increases by 2 every minute.
