Mnenie [13.5K]

Answer:

The correct option is A.

Explanation:

The number of bacteria in an experiment can be represented by an exponential function

f(x)=4^x

where, x represents the number of hours.

We need to find the value of x when f(x)=64.

Substitute f(x)=64 in the given function.

64=4^x

It can be rewritten as

4^3=4^x

On comparing both sides by get

3=x

The value of x is 3.

Since f(3)=64 it means the population of bacteria is 64 in 3rd hour.

Therefore the correct option is A.
