According to the graph we have:
Domain are the values of x. We can see that the graph extends horizontally from -5 to 3, but -5 and 3 are not included. Then, the domain is
Range are the values of y. Therefore, we see that the graph extends vertically from 4 to -3, so the range is:
Answer:
a. domain = (-5, 3)
b. range = (-3, 4)
