Question

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

Explanation:

Step1: Define the horizontal line test

A function is one-to-one if every horizontal line intersects its graph at most once.

Step2: Analyze the first graph

A horizontal line at \(y = 2\) intersects the parabola twice, so it is not one-to-one.

Step3: Analyze the second graph

A horizontal line at \(y = 0\) intersects the wave-like curve multiple times, so it is not one-to-one.

Answer:

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