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

  . 
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

y = |x| - 7 makes the graph slide . . .

• left 7
• right 7
• up 7
• down 7

y = |x - 3| makes the graph slide . . .

• left 3
• right 3
• up 3
• down 3
