Graphing Piecewise and Step Functions

The graph and equation of a piecewise function are shown. Which are the values of a, b and c?

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 this type of function called?

• Discrete Function 

• Segment Function

• Step Function

• Jump Function

Use the graph to evaluate f(5)

• 0

• 2

• 4

• 6

• $12.75
• $35
• $43.40
• $27.75

Find f(2)

• f(2) = 0

• f(2) = 1

• f(2) = 3

• f(2) = 4

What is m(4) if:

• -3

• 0.5

• 0

• -3.5

What is m(-3) if:

• -3

• 0.5

• 3

• -3.5

Using the pictured graph, what is f(-3)? 

• -3

• -1

• 1

• 3

Find f(2)

• 3

• -2

• 2
