Answer:
a) Function? No
b) Domain: 
c) Range: 
Step-by-step explanation:
a) Function? No
We want to determine whether the graph of the relation is a function or not.
When we draw a straight line at x=-1, it will intersect the graph at several points, therefore the graph fails the vertical line test and hence it is not a function.
b) The domain refers to all x-values for which the function is defined.
From the graph the domain is
because the ends of the graph are closed.
c) The range is the set of all y-values for which the graph is defined.
From the graph the range is 
Is the question asking to make up an equality that, in essence, is anything but x+3<0?
In that case:
2x+9<0
2x<-9
x<-9/3
x<-3
I think it’s A. If not, then B.
Answer:
the distance formula is square root (x2-x1)^2 + (y2-y1)^2
7^2 + 4^2 = 49+16 = 65
squarroot of 65 = 8.06
