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
