Understanding functions

Are these functions inverses of each other?

• Yes

• No

Are these inverses? f(x)=x+7 and g(x)=x-7

• No

• Yes

• I don't know

What is the best description?

• They are both functions, but not inverse functions.

• They are inverse functions.

• They are reflected over y=x, but they are not both functions.

• They are not reflected over y=x, and they are not both functions.

• Yes, the functions are inverses.

• No, the functions are not inverses.

• Inverse Functions

• Not Inverse Functions

Which of the following graphs show the correct graphs of the original and inverse.

Are the following inverses of each other?

Are the following inverses of each other? Use composition of functions. f(g(x)) and g(f(x))

• True

• False

A function has an inverse if: f(g(x) = x

• True

• True, if x = 1

• True, if g(f(x) = x

• False, an inverse never = x
