Function Example Ideas: Tips, Suggestions, and Help

In summary, the conversation discusses the concept of functions and how they relate to the domain and range. The idea that if a function is not onto, any element in the range will have an empty inverse set is mentioned. The conversation ends with a suggestion to consider any function that is not onto.

I need help getting some ideas for an example of a function.
Any help, ideas, suggestions, and/or tips are greatly appreciated.
Thanks for looking at this question!

You are sort of muddling up domain and range. If f:A->B then H must be a subset of the range B, right? And if b is an element of B such that there is no a such that f(a)=b you are defining f^(-1)({b})={} (the empty set). Also correct? Then just consider any function that isn't onto. Any one. You pick.

What is a function example?

A function example is a specific instance or demonstration of a function in action. It is used to show how a function is designed and how it works in different scenarios.

Why are function examples important?

Function examples are important because they provide a clear and practical understanding of how a function can be used. They can also help in troubleshooting and debugging code.

How do I create a function example?

To create a function example, you first need to define the function and then provide input values to test the function. You can use different scenarios and inputs to demonstrate the function's capabilities.

What makes a good function example?

A good function example should be concise, clear, and relevant to the function being demonstrated. It should also cover multiple use cases and highlight the key features and benefits of the function.

Can I use function examples from other sources?

Yes, you can use function examples from other sources as long as you give credit to the original source. However, it is always best to create your own function examples to ensure they are relevant and accurate for your specific needs.
