A test to check if the relation is a function called

• Horizontal Line test

• Vertical Line test

• None of these

If the function fails Horizontal Line Test then

• The function is one-to-one

• The function is NOT one-to-one

• The function will have more than one point of intersection with the Horizontal Line

• It is not a function
