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

What is the equation and domain of the blue piece, labelled as "A"?

• f(x) = x + 1, x ≤ –1

• f(x) = x + 2, x ≤ –1

• f(x) = x + 2, x < −1

• f(x) = x + 2, x ≥ − 1

What is the equation and domain of the green piece, labelled as "C"?

• f(x) = 3x + 1, x ≥ 1

• f(x) = 3x − 2, x ≤ 1

• f(x) = 3x – 1, x ≥ 1

• f(x) = 3x – 2, x ≥ 1
