The use of 'to + V + O'?

Hello! There's something in a sentence that I'm curious about... Here I have some examples.

1. She returned home early to cook dinner for her family.
2. She made an appointment with a doctor to have her hearing checked.

What are the function of the senteces 'to cook dinner for her family' and 'to have her hearing checked' as? Are they noun clause? Because they have their own verb and object, right...?

Thanks in advance!
