Help me please help.

steps below

Step-by-step explanation:

This is a contradictory proof of sophistry

f(x+4) = f(x)+f(4)  ...(1)     when x=0

f(x+4) = f(0+4) = f(4) = f(x) + f(4)

f(x) = f(4)-f(4) = 0

From (1): f(x) = f(x+4) - f(4)

x=-4       f(-4) = f(-4+4) - f(4) = f(0) - f(4) = -f(4)   ...(2)

From (1): f(x+4) = f(x)+f(4)

x=4         f(4+4) = f(8) = f(4) + f(4) = 2f(4) = -2f(-4)   from (2) ... (3)

f(8) +2f(-4) = -2f(-4) + 2f(-4) = 0

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.

the answer should be a. snail
