Suggest a real-world situation that could be described using a piecewise-defined function with either two or three pieces. Write the function and name it r (x). Do the necessary research to find a range of numbers that would be realistic inputs to your function. Give an example input and use it to solve your function, determining the corresponding output. Give your answer in a paragraph, being sure to include each of the following items:

The definition of your piecewise-defined function r (x), which should include either two or three pieces.

A real-world situation that can be modeled by your function r (x).

A realistic domain for your function r (x).

A sample input/output pair for your function r (x).

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
