The Concept of Inverses

Which notation is used to describe the inverse of g(x)?

• f(x)

• f^-1(x)

• y

• g^-1(x)

If the graph of f(x) goes through (1, 4) and (4, 6), what points does the graph of f^-1(x) go through?

• (1, 4) and (4, 6)

• (-4, -1) and (-6, -4)

• (-1, -4) and (-4, -6)

• (4, 1) and (6, 4)

are these inverse functions?

• no
• yes
• no way to tell

What does it mean to find the inverse of a function?

• Each output becomes the input into the inverse.

• All the inputs and outputs become negative

• Each input goes into two different functions.

• The function and the inverse are the same "machine"

• 
• 

Do these tables show a function and its inverse?

• yes

• no
