The population decays by a factor of (1/2 )^1/4 every hour.
<h3>
Exponential Function</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value of y, b is the multiplier, y and x are variables.
Let y represent the bacteria population after x hours.
A bacteria population decreases by a factor of 1/2 every 4 hours.

The population decays by a factor of (1/2 )^1/4 every hour.
