Answer:
D
Step-by-step explanation:
The range of a graph is the span of y-values it covers.
From the graph, we can see that the span of y-values covered goes from y=-3 all the way to y=3.
However, note that at y=-3, while it is a closed circle, it is an open circle at y=3.
This means that we do <em>not</em> include y=3 in our range, but we <em>do</em> include y=-3 in our range.
So, our range is all values between -3 and 3 including -3.
In set notation, this is (and remember since this is the range, to use y):
So, our answer is D.
And we're done!
