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

Evaluate the function when x = 2  {HINT: Should you substitute into the top equation or the bottom equation?}

• f(2) = 2(2) - 5 = 1

• f(2) = 2(2) - 5 = -1

• f(2) = ½(2) + 1 = 2

• f(2) = 4
