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}

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

• 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
