One purpose of General T. Sherman's march to the sea was to a) break the spirits of confederate citizens
b) allow troops under his control to get rest
c) find ships and sail his soldier's to the north
d) prove that he was the most skilled union general

A

Step-by-step explanation: He slashed across the South destroying farms and land in a scorched Earth tactic, which was really damaging to the South because the land they had was all they had.

It's not B because they didn't need rest, he wasn't sailing North so it's not C, and he didn't have anything to prove himself as a skilled general, he already was a skilled general.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
