===================================================
Explanation:
The range is the set of all possible y values of a function.
The lowest point happens when y = -3. We exclude this y value because of the open hole.
The highest point is at y = 3 which is included because of the filled in circle.
The range can be written as meaning y is between -3 and 3, excluding -3 but including 3.
Side note: The range in interval notation is (-3, 3].

Answer:
Step-by-step explanation:
If I'm not mistaken by the question, we have
Multiply through by the LCM of all the denominators to clear the fractions. Since we have only one fraction, we multiply through by its LCM (3)
Putting all terms on the LHS (left hand side) and evaluating,
It is given in the question that
And
can also be written as
Therefore,
That gives,
