Answer:
The correct answer is option B.
Step-by-step explanation:
To find the range of the function whose graph is known, then we will use the graphical approach but can also use the algebraic approach.
Here the range is found by finding the minimum value of the function and the maximum value f the function, using the graph.
Here we can see that from the graph that the maximum value of the function is y=9 and the minimum value is y=-6, also there is no breaking point in the graph of this function.
So the range of the function is:
[tex]-6 \leq y \leq 9[/tex]
and this is given by option B.
