Step 1: Examine the first graph.
A one-to-one function is also called an injective function, which means that each element in the range corresponds to exactly one element in the domain. In this graph, we see that every x-value has only one corresponding y-value, and there are no horizontal lines that intersect the graph more than once. Therefore, this function is one-to-one.
Step 2: Examine the second graph.
This function also has the property that each x-value corresponds to only one y-value, and there are no horizontal lines that intersect the graph more than once. Therefore, this function is also one-to-one.
Final Answer
The one-to-one functions are the first graph, the second graph, and the fifth graph.
