What is the parent function of an Inverse Variation Function?

Which graph below shows an inverse variation function?

• 
• 
• 
• 

Match the equation with the graph

• y = √(x-1) - 1
• y = √(x+1) - 1
• y = √(x-1) + 1
• y = √(x+1) + 1

• x = 49
• x = 53
• x = 45
• x = 18

Given (32, 15) and (12, y). Find the constant k of inverse variation, and then find the missing y value.

• 40
• 48
• -40
• -48

What type of variation?

• Direct

• Inverse

• Neither

What type of variation?

• Direct

• Inverse

• Neither

What does the Direct Variation Equation look like?

• y= kx
• y = mx + b
• y = b
• y = x

Which of the following is NOT a direct variation?

• y = -2x
• y = 1/2x
• 2x + 3y = 2
• 3y = 4x

What ordered pair does a direct variation always go through when graphed?

• (0, 0)
• (1, 0)
• (0, 1)
• (1, 1)
