The function f (x) = 30 (1.4) x gives the number of bacteria in a science experiment, where x is the number of days after the start of the experiment. To the nearest whole number, how many bacteria will there be after 4 days?

115 bacteria

Step-by-step explanation:

The function that gives the number of bacteria in a science experiment is:

f (x) = 30 (1.4) ^x

Where x is the number of days

After 4 days (x = 4), the number of bacteria will be:

f (4) = 30 * (1.4) ^4

f (4) = 39 * 3.8416

f (4) = 115.248 = 115 (To the nearest whole number)

The number of bacteria after 4 days is 115.
