Exploring Inverse Functions and Their Properties

What is the result when you apply an inverse function to the output of its original function?

What is the relationship between the domain of a function and the range of its inverse?

• There is no relationship

• They are identical

• The domain of one is the range of the other

• They are inversely proportional

How do you find the inverse of a function algebraically?

• By subtracting the original function from one

• By swapping the variables and solving for the new variable

• By taking the square root of the original function

• By dividing by the original function

What must be true for a function to have an inverse?

• It must be a polynomial of degree 2 or higher

• It must be a linear function

• It must be possible to solve for the variable after swapping

• It must pass the vertical line test

Why can't some functions have inverses?

• Because they are not continuous

• Because they are too complex

• Because they don't pass the horizontal line test

• Because they can't be solved for the variable after swapping

How can you verify that two functions are inverses of each other?

• By subtracting one from the other

• By adding them together

• By dividing one by the other

• By applying one after the other and checking if the input is retrieved

What happens to the graph of a function when you reflect it across the line y = x?

• You get its inverse function

• The graph remains unchanged

• You get a completely unrelated graph

• The graph becomes a straight line
