Answer:

4 and 5 not functions 6 function

Step-by-step explanation:

In a function, each x value can only have one y value. To test this, you can try the vertical line test. Put a vertical line on the function; if it touches only one point the graph is a function. For graph 4, the x value of 3 has y values of 1 and 4 so it is not a function. For graph 5, the x values of 1 and 5 have many y values so the graph isn't a function. For graph 6, each x value has only one y value so it is a function.

Answer:

4. Not a function

5. Not a function

6. Function

Step-by-step explanation:

1 -3 (correct!)

Functions do NOT have repeating x-values. Hence why you were able to determine if # 1-3 are fuctions or not.

4. Not a fuction:

(1, 2)

(2, 3)

(3, 1)

(3, 4)

As we can see, both points have the same x-values. Therefore, not a function.

5. Using our knowledge about functions, we can quickly tell that this graph is NOT a fuction.

There are many points that fall under the same x-value.

6. Function:

(1, 2)

(2, 2)

(3, 3)

(4, 4)

No repeating x-values. Therefore, a function.

Hope this helps!
