Piecewise Function Practice

Which "piece" of the function would you use to evaluate the piecewise function for f(-4)

• $-2x+1$

• $5x-4$

Which of the piecewise functions matches this graph?

• 
• 
• 
• 

The graph represents a piecewise function. How many pieces make up the function?

• 1

• 2

• 3

• 4

The equation of the red piece is y = 1. What is the domain of the red piece?

• x > –1

• x < –1

• x < –1 or x > 1

• –1 < x < 1

What is the equation of the absolute value function?

• f(x)= |x+4|
• f(x)= |x-4|
• f(x)= |x| + 4
• f(x)= |x| - 4

Which graph matches the function:
y = -2|x - 3| + 5

• A
• B
• C
• D

  . 
The blue graphs is the parent function f(x)=|x|, the red must be

• g(x)=|x+2|
• g(x)=|x|+2
• g(x)=|x-2|
• g(x)=|x|-2
