The upper bound and lower bound of the parameter h will be 0 and 48.
A statement, principle, or policy that creates the link between two variables is known as a function.
Suppose you went on vacation but forgot your smartphone charging cable.
Your phone battery died after 2 full days (48 hours) of use.
This situation is modeled by the equation:
f(h) = (48 – h) / 48
where h is the hours of cell phone use and f(h) is the percentage of battery left.
Then for upper and lower bound, the value of f(h) will be 0 and 1.
For upper bound, we have
0 = (48 – h) / 48
h = 48
For lower bound, we have
1 = (48 – h) / 48
h = 0
