What are the inverse points for the coordinates:

(3, 0) , (2, -4), (5, 5) and (-6,8)

• (3,0) , (2, -4) , (5,5) , (6,8)

• (0,3) , (-4,2) , (5,5) , (8,-6)

• (3,2), (0, -4), (5, -6), (5,8)

The inverse has been reflected over which line?

• y = x

• x = 0

• y = 0

• x = -y

Which graph represents the functions f(x) and f^-1(x)?

• 
• 
• 
• 

Find the inverse of f(x) = -4x - 12

• f^-1(x) = 4x -3

• f^-1(x) = (x+12)/-4

• f^-1(x) = 4x+12

• f^-1(x) = -4x - 3
