Piece-Wise Functions

Evaluate f(-5)

• 0

• 2

• 5

• -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  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

A piecewise function (f(x)) is shown in the graph. What is f when x equals 0?

What is f(1)?

• 3

• 1

• 0

• 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.
