The graph is a function because when you use the vertical line test it does not hit more than one point at any given place on the line.

16x2=32
21x2=42
32+42=54
the perimeter is 54
Answer:
B.
Step-by-step explanation:
Here the best method to solve is by substituting the end values of the set in each option , otherwise it will a time consuming problem.
Now substitute x=-4 in all the options
A.
16+8-8=16>0
so out of option A and C option C is correct.
B.
16-8-8=0 which means for the values of x>-4
is less than 0
Now substitute x=2 in all the options
A.
4-4-8=-8<0 . so option A and C both are incorrect.
B.
4+4-8=0 which means for the values of x<2
is less than 0
Therefore the correct option is B
Every transformation like

translated the graph vertically, k units up if k is positive, k units down if k is negative.
So, in your case, we have that
is the same graph as
, except it's shifted 1 unit down.
