Absolute Value Review

What is the equation of the graph below?

• f(x ) = I x + 2 I - 4
• f(x ) = -I x - 2 I + 4
• f(x ) = I x - 4 I + 2
• f(x ) = -I x + 4 I + 2

Identify the graph of y = |x + 4| by translating y = |x|.

• 
• 
• 
• 

The center point of an absolute value graph is called it's vertex. Using your x/y table, determine where the vertex of the equation y = |x| would be.

• It's impossible to know

• (0,0)

• (1,0)

• (0,1)

Using the x/y table again, what do you think the slopes of the equation y = |x| are?

(Since it forms a V shape, there are 2 slopes)

• It's impossible to know.

• 1 and -1

• 1/2 and -1/2

• 0 and undefined

What is the domain of the absolute value function?

• (4, 0)
• (0, 4)
• (-infinity, infinity)
• [4, infinity)
