The carpenter’s chronicle charges $12 for each of the first three lines of a classified ad and $7.25 for each additional line. express the cost of an x-line ad, c(x), algebraically as a piecewise function.

The required piecewise function is

Step-by-step explanation:

It is given that the carpenter’s chronicle charges $12 for each of the first three lines of a classified ad.

For 0 ≤ x ≤ 3, the cost function is

Carpenter’s chronicle charges $7.25 for each additional line after 3 lines.

For x > 3, the cost function is

Therefore the required piecewise function is

answer: its the third option.
