Functions Real World Graphing Scenarios

Match the following piecewise functions with their correct conditions for calculating rewards points:

• -x+1 if x ≤ $100; x if x > $100

• f(x) = { -x+1  if x < $100;  x  if x ≥ $100

• -x+1 if x < $100; x if x ≥ $100

• f(x) = { x  if x ≤ $100;  -x+1  if x > $100

• x if x ≤ $100; -x+1 if x > $100

• f(x) = { x  if x < $100;   -x+1  if x ≥ $100

• x if x < $100; -x+1 if x ≥ $100

• f(x) = { -x+1  if x ≤ $100;  x if x > $100
