Now, remember that is always non-negative, so
for any value of
. This means
for any
, and so
i.e. f(x) is at most -6, and hence negative for all .
The real world example for the absolute value are to express the change in balance of account.
How to use absolute value in real world problem?
Absolute value in real world problem is used to express the change or variation from one point to another point. In the absolute value, the sign of the number is not consideredd.
Let a real world example-
- Everyone is going with 20 km/h and a person x is going with 15 km/h.
- The person x has most likely to get the token as the difference between his speed and public speed is 5 km/h.
- The sign of the number is not considered, whether it is +5 or -5 it is the difference of 5 km/h.
- The number line for this absolute value is plotted below.
