Question

What is the range of the function graphed below?

Answer 1

To find the range of a function what you have to take into account are all the values of y that the function takes.
 We have then that in this case the values are:
 from y = 3 (included)
 up to y = -3 (not including it)
 The range of the function is:
 -3 <y <= 3
 Answer:
 the range of the function graphed below
 -3 <y <= 3

Answer 2

The range is -3 < y ≤ 3
