Answers:
- Function? No, it's not a function
- Domain: {15}
- Range: {0, -2}
===============================================
Explanation:
The domain consists of the set of x coordinates of each point. In this case, we only have one x value listed. The domain is {15}. Use curly braces even if there's only one item. This tells the reader we have a set.
The range is {0,-2} to indicate the y coordinates of the two points.
We don't have a function because x = 15 repeats itself. The input x = 15 leads to multiple outputs at the same time, which isn't allowed if you want a function. You can use the vertical line test as a visual way to see that we don't have a function.

Answer:
x=16/9
Step-by-step explanation:
1/3+7=3(x+2/3)
1/3+21/3=3x+6/3
22/3=3x+2
3x=22/3-2
3x=22/3-6/3
3x=16/3
x=(16/3)/3
x=(16/3)(1/3)
x=16/9
