no additional details were added for this assignment.

select all of the following graphs which are one-to-one functions.

Explanation:

Step1: Define vertical line test

A graph represents a function if every vertical line intersects it at most once.

Step2: Analyze the first graph

The first graph is an ellipse, which fails the vertical line test and is not a function.

Step3: Analyze the second graph

The second graph is a wave, which passes the vertical line test but fails the horizontal line test.

Step4: Determine one-to-one status

Since neither graph is both a function and passes the horizontal line test, neither is one-to-one.

Answer:

None of the given graphs are one-to-one functions.
