Answer:
Bottom answer
Step-by-step explanation:
Although I cannot see the answer labels, the answer is the very bottom graph. The way you can find a functional graph is if you add vertical lines going down and that there is only one point that crosses it, not two. It is kind of difficult for me to explain, so if you need help, I suggest you look up how to know when a graph is a function or not.
Since both of the numbers have a variable which is x ready to be multiplied, there is no expression leading to the variable therefore you will add normally but you will need to put the missing variable which needs to be multiplied. So overall you can just add and once you get your variable you can be abe to multiply and get your final answer.
Hope this helps
