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.

The glaciers are a frozen ice mass that is slowly moving from a higher toward a lower region. For them to exist, specific conditions are required, the most important of which is that the climate is very cold throughout the whole year. The places that provide suitable conditions for the existence of glaciers are the Antarctica (where most of them are located), the island of Greenland, as well as the very high mountains that have cold weather throughout the whole year, especially at their highest parts, like the Alps and the Himalayas.
