Answer:
The first picture is a function and the second picture is not.
Step-by-step explanation:
Reason - In the first picture, there is no repeating value of x. In other words, every x value has a y value. However, in the second picture, the x value, 2 goes to 2 and -3.
5 is correct! the real answer is 4.80
The value would be 5 itself because it is in the ones place. If it were in the tens place it would be 50, if it were in the hundreds place it would be 500, and so on. Hope this helps. Let me know if you need anything else or if I can clarify anything for you, and feel free to post more questions.
