Inverse Functions and Graphs

The inverse has been reflected over which line?

• y = x

• y =1

• y = 0

• y = x + 1

Are these functions inverses?

• Yes

• No

Are the blue and red graphs inverse functions?

• Yes, the functions reflect over y = x

• No, they do not reflect over the x - axis.

• No way to tell from a graph
