Multiple Choice

On the graph, which portion of the piecewise function is represented in red?

• x
• 0.5x + 2.5       
• -1
• 0.5x + 2

Multiple Choice

For the graph shown. Which selection is the correct way to write the piecewise function?

Multiple Choice

What are the domain restrictions for the middle piece of this function?

• x ≥ 1
• x ≥ 2
• 2 ≤ x < 6
• 1 ≤ x < 3

Multiple Choice

What is the domain restriction of the blue piece of this function?

• x > 0
• x ≥ 0
• x > 2
• x ≥ 2

Multiple Choice

What is the equation of the RED piece (one on the RIGHT)?

• x - 1  if x > 3
• 3  if  x ≥ 3
• -1  if  x ≥ 3
• -1  if  x > 3

Multiple Choice

• (1/3)x if {x<-3}

  x² - 4 if {-3≤x<1}

  √x if {x≥1}

• (1/3)x +3 if {x<-4}

  x² - 4 if {-4≤x<4}

  √x if {x≥0}

• (1/3)x +2 if {x<-3}

  x² - 4 if {-3≤x<1}

• (2/3)x +2 if {x<-5}

  x² - 4 if {-3≤x<1}

  √x if {x≥1}

Multiple Choice

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
