Piecewise Work

Which of the following represents this peicewise graph

• 
• 
• 
• 

Which piecewise function corresponds to this graph? (Take your time)

• f(x) = { x  if x < 4;   -x+1  if x ≥ 4

• f(x) = { x  if x ≤ 4;  -x+1  if x > 4

• f(x) = { -x+1  if x < 4;  x  if x ≥ 4

• f(x) = { -x+1  if x ≤ 4;  x if x > 4

State the domain of the following Piecewise Function:

• D: x = All real numbers

• D: y = 2 or  y < 0

• None of these are correct.

Find f(0)

Which graph matches: -x+4 if x < 2 2x-6 if x ≥ 2

• A

• B

• C

• D

• $12.75
• $35
