• f(5) does not exist

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 graph matches:
4-x for x<2
2x-6 for x>=2

• A

• B

• C

• D

Given the piecewise equation evaluate both f(0) and f(-1)

• f(0) = 1

  f(-1) = 2

• f(0) = -4

  f(-1) = -5

• f(0) = -4

  f(-1) = 2

• None of these are correct.
