Answer: 72 ft
Step-by-step explanation:
Given
The width of a post is 
Posts are separated by 
chain
for 2 posts, length is 
for 3 posts, length is 
for 4 posts, it is 
i.e. 11 ft is adding on the addition of another post
for 7 posts it is 
Thus, the total length of the fence is 
F ( -1 ) = 2 · ( -1 )³ - 3 · ( -1 )² +7 =
= 2 · ( -1 ) - 3 · 1 + 7=
= - 2 - 3 + 7 = 2
