Looking around in your own country, discuss one practical application in which “piecewise functions” are used either explicitly or implicitly.
Example to be used- A paid parking lot based on length of time stayed, up to half an hour cost $1, over half an hour up to an hour cost$2.50 and over an hour and up to 15 hours cost $20. ### Answer & Explanation Usamah Prosser Skilled2021-02-01Added 86 answers Step 1 One practical application in which ''Piecewise functions'' are used either explicitly or implicitly. Step 2 1. A cell phone company uses the function below to determine the cost, C, in dollars for g gigabytes of data transfer. $C\left(g\right)=\left\{\begin{array}{cc}25& 0 Find the cost of using 1.5 gigabytes of data and the cost of using 4 gigabytes of data. Solution: To find the cost of using 1.5 gigabytes of data, we first look to see which part of the domain our input falls in. Because 1.5 is less than 2, we use the first formula. To find the cost of using 4 gigabytes of data, , we see that our input of 4 is greater than 2, so we use the second formula. C(4)=25+10(4-2)=$45

Example to be used-
A paid parking lot based on length of time stayed, up to half an hour cost $1, over half an hour up to an hour cost$2.50 and over an hour and up to 15 hours cost \$20.
Solution:
Let the number of hours be x then the piecewise function,
$f\left(x\right)=\left\{\begin{array}{cc}\frac{1}{5}& \phantom{\rule{1em}{0ex}}\text{if}\phantom{\rule{1em}{0ex}}0
