How to create new function in parent theme?

Can you partially override a function in a parent theme?
Strictly speaking, you can’t partially override a function. You can only let it run or disable it. But there are workarounds.

You might find that the function includes a call to another pluggable function from within the parent theme.

How are action and filter hooks hooked in WordPress?

If you make changes to a theme’s files directly (i.e. anything within the /themes/yourthemename/ directory), those changes are likely to be overwritten when you next update the theme. A child theme in WordPress would inherit all the functionality, features, and the code of the parent theme without making any changes to the parent theme itself.
