Hi!
A function is when you can look at any number on the graph, and it only has one value in the line. For example, look at 2 on the y-axis. It only has one point on the line, but -2 on the y-axis has two points on the line. I hope that makes sense.
Therefore the answer is B. No, because some of the y-values are paired with 2 x-values.
Hope this helps! :)

4 * side^2 = diagonal1 ^2 + diagonal2 ^2
4 * side^2 = 12^2 + 16^2
4 * side^2 = 144 + 256
4 * side^2 = 400
side^2 = 100
side = 10
So the perimeter = 4*10 = 40
The first and the third one because they equal each other
2x+2=2(x+1) and 3(x-1)=3x-3
