Is it ever possible for the domain and range in a function to have different numbers of entries (for example, 3 domain entries to 5 range entries, or 2 range entries to 7 domain entries)? What happens when this is the case?

Answers

No , & More Than Likely If It Is To Happen It's Because The Domain Entry Repeated A Number Mulitiple Times

Final answer:

The number of entries in the domain and range of a function can be different. Some inputs in the domain may have the same output in the range, or some outputs in the range may have no corresponding inputs in the domain.

Explanation:

In a function, the number of entries in the domain and range can be different. This happens when there are multiple inputs that map to the same output or when there are outputs with no corresponding inputs.

For example, consider the function f(x) = $x^2$ . The domain can be any real number, but the range is only non-negative real numbers (including zero). So, there are more entries in the domain than in the range.

When this is the case, it means that some inputs in the domain have the same output in the range, or some outputs in the range have no corresponding inputs in the domain.
