Final answer:
A single point where d(-6) = 300 does not provide enough information to determine if the function is linear or to define the full domain and range. We only know that -6 is in the domain and 300 is in the range, but we cannot infer the types of these sets or the form of the function from this point alone.
Step-by-step explanation:
The question asks what can be inferred about a function given that d(-6) = 300. This tells us that when the input (from the domain) is -6, the output (from the range) is 300. However, this information alone does not tell us enough to determine the type of function it is, whether it is linear or otherwise. It simply tells us a single point that exists within the function.
To determine if a function is linear, we would need at least two points and check if the rate of change between those points is constant. Since we only have one point, we cannot conclude it is linear (Option A). We also know that the function has a domain that includes -6 and a range that includes 300, but neither is exclusively the domain nor the range (Options B and C are incorrect). Therefore, option D is also incorrect as it implies exclusivity. Without additional information, we cannot infer much more about the function.
