Is this a function and can you explain how if it is?
ANSWER ASAP

It is function.

Step-by-step explanation:

Function is they don't have same repeating x values in tables, graphs, and coordinates. In this question, they give you the equation. But if you look at closely, it is linear equation! That means that when you graph this equation, you will get straight line. So, straight line can't get same x values, it is function.
