Answer:

General Formulas and Concepts:

<u>Algebra I</u>

  • Vertical Line Test - A function's x-values must have only 1 y-value corresponding to it. If the function fails to pass this, it is not a function.

Step-by-step explanation:

When we apply the Vertical Line Test to the 1st graph, it does not pass it. Therefore, the 1st graph is not a function.

When we apply the Vertical Line Test to the 2nd graph, it does not pass it. Therefore, the 2nd graph is not a function.

When we apply the Vertical Line Test to the 3rd graph, it does not pass it. Therefore, the 3rd graph is not a function.

When we apply the Vertical Line Test to the 4th graph, it does pass it. Therefore, the 4th graph is a function.
