Examine the graphs of each relation below. Decide if each is a function. Then describe the domain and range of each.

See below

Step-by-step explanation:

Graph a:

It is not a function as it fails the vertical line test.Domain and range both are within -3 and 3: x, y = [-3, 3]

Graph b:

It is a function as passes the vertical line test.

The domain, the set of x- values:

x = [-2, 3]

The range, the set of y-values:

y = [-2, 2]
