Answer:
- 2
Step-by-step explanation:
The composition of inverse functions gives x
g(x) and 
(x) are inverse functions, then
(g(x)) = x , thus
(g(- 2)) = - 2
The range of a function is the set of numbers used as y-coordinates.
Let's look at the y-coordinates of the points in the graph.
There are points in the graph with all y-coordinates greater than -3.
There are points in the graph with all y-coordinates less then -3.
At exactly -3, there is no point on the graph with that y-coordinate.
We expect the graph to behave as it is shown above 7 and below -7, so the only value excluded from the y-coordinates is -3.
Answer: B. All real numbers except -3
