Answer
Option C is correct.
Range = All real numbers greater than or equal to 0 and less than or equal to 9.
Step-by-step explanation
The range of a function refers to the region of values where the function can exist. It refers to the values that the dependent variable [y or f(x)] can take on. It is the region around the y-axis that the graph of the function spans.
So, the range for this question will be all the real numbers greater than or equal to 0 and less than or equal to 9 according to the graph.
