Answer:
The graph in the attached figure
Step-by-step explanation:
we have

The function represents an inverted V-shaped graph
The vertex of the function is the point (2,-1)
The y-intercept of the function is the point (0,-3)
The domain is all real numbers -----> (-∞,∞)
The range is all real numbers less than or equal to -1 ----> (-∞,-1]
Using a graphing tool
The graph in the attached figure
If an is a5
and
an-1 is a4
then using your recursive formula for an arithmetic sequence
an=an-1 +d
then
a5=a4+d
now, a4 =6 and common difference "d" is d=-11
hence
a5=6 -11
6-11= -5
