Apply inverse variation to a real-life scenario: If the number of workers is inversely proportional to the time taken to complete a task, and 8 workers can complete the task in 6 hours, how long will it take for 12 workers to complete the same task?

• 10 hours

• 4 hours

• 5 hours

• 2 hours

Analyze the inverse variation data: Given the data points (2, 8), (4, 4), (8, 2), determine if they represent an inverse variation relationship and find the constant of variation.

• No, the data points represent a direct variation relationship with a constant of variation of 4.

• Yes, the data points represent an inverse variation relationship with a constant of variation of 16

• Yes, the data points represent an inverse variation relationship with a constant of variation of 2.

• No, the data points do not represent any type of variation relationship.

Y varies inversely with x, and y is 0.5 when x is 4. Which equation represents this situation?

• y=2x

• y=2/x

• y=4x

• y=x/2

If x and y are in an inverse variation then which of the following is correct?

• x - y = constant

• x + y = constant

• xy = constant 

• x⁄y is constant 

What is the parent function of an Inverse Variation Function?
