Question

Please help me solve this​

Answer 1

Answer:

a) Function? No

b) Domain: $-4\le x\le 2$

c) Range: $-3\le y\le 3$

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 $-4\le x\le 2$ 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 $-3\le y\le 3$
