Final answer:
To determine if a function is invertible, it must be both one-to-one and onto. Without this information, it is insufficient to determine if the function is invertible or not.
Step-by-step explanation:
In order for a function to be invertible, it must be both one-to-one and onto. A function is one-to-one when each element in the domain maps to a unique element in the range. A function is onto when every element in the range has a corresponding element in the domain.
If a function is not one-to-one, there are multiple elements in the domain that map to the same element in the range. If a function is not onto, there are elements in the range that do not have a corresponding element in the domain.
Therefore, in order to determine if a given function is invertible, we need to know if it is one-to-one and onto. Without this information, it is insufficient to determine if the function is invertible or not. The correct answer is d) Insufficient information provided.
