Question

Prompt

A polygonal chain is a connected series of line segments whose length is defined as the sum of the lengths of the line segments it is made of. A polygonal chain with a length of 33 centimeters (cm) is extended by adding line segments that each have a length of

8 - r

cm. Which function

f

represents the total length, in cm, of the extended polygonal chain after

x

line segments are added?

f (x) = 33 (8 - r) + x

f (x) = 8 x - r x + 33

f (x) = 8 x - r + 33

f (x) = (41 - r) x
