Use the graph to determine whether the inverse of f(x) is a function. Explain your reasoning.

• The inverse is not a function because f(x) does not pass the horizontal line test.

• The inverse is a function because f(x) does not pass the horizontal line test.

• The inverse is not a function because f(x) passes the vertical line test.

• The inverse is a function because f(x) passes the vertical line test.

Is the inverse of this a function?

• No

• Yes
