Answer:
The correct option is D.
Step-by-step explanation:
The given graph is the graph of a cosine function, which shifts 1 unit left.
The cosine function is defined as

Where, a is amplitude, b is frequency, c is phase shift and d is vertical shift.
If c>0, then the graph shifts c units left and if c<0, then the graph shifts c units right.
Since the graph show only phase shift and the graph shifts only one unit left, therefore required function is

Option D is correct.
Answer:
True
Step-by-step explanation:
Ok so I name them Bob, Joe, and Harry
if total perimiter=14 then
Bob has legnth of 1 and width of 1
Joe has legnth of 1 and width of 1
Harry has legnth of 2 and width of 1
if each rectangle has perimiter of 14 then
Bob has legnth of 4 and width of 3
Joe has legnth of 5 and width of 2
Harry has legnth of 6 and width of 1
