<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
Given the function for the substance as
, therefore, the half life of the substance can be written as,

Since we need to find the half life, therefore, the ratio of the initial mass and the mass after half-life will be 1/2.

Given the value of k is 0.1109, therefore,

Hence, the half life of the substance is 6.25 days.
