Question

Prompt

The number of cells of the bacteria Bacillus megaterium doubles every

25

minutes during its growth period when placed in a medium of sucrose-salts in a controlled laboratory environment. If a sample of

980

cells of Bacillus megaterium is placed in sucrose-salts in a controlled laboratory environment, which function

f

best represents the number of cells of the bacteria

x

minutes after the growth period begins, where

x

is less than the number of minutes in the growth period?

f (x) = 980 (1/2)^{x /25}

f (x) = 980 (2)^{x /25}

f (x) = 980 (1/3)^{x /25}

f (x) = 980 (3)^{x /25}
