Inverse Functions Through a Point

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

• f(x)

• f^-1(x)

• y

• g^-1(x)

Do these mappings show a function and its inverse?

• No

• Maybe

• Yes

• There is not enough information to tell

What are we learning about in Algebra 2 class right now?

• Types of lines

• Types of graphs

• Functions and inverse functions

• Types of angles

If the point (-7,5) lies on the graph of f(x) , which of the following points must lie on the graph of its inverse?

• (5,-7)

• (-1/7,1/5)

• (7,-5)

• (1/7,-1/5)

Are these the graphs of two inverse functions?

• Yes

If the equation of f(x) goes through (1, 4) and (4, 6), what points does 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)

Select the table that represents the inverse of this relation:

• 

TRUE or FALSE
If f is an invertible function and f(a) = b, then f^-1(b) = a.

• TRUE

• FALSE
