I read that the word as is usually followed by a verb, whereas the word like
by a noun. I'd like some advice for the following sentence:
I don't see her as a teacher, I see her as a friend.
Is the use of as here used correctly, if it refers to the function of the teacher and the friend in general or the word like would be accurate?
You only have half of the rule. Traditionally, "like" should only be a used as a preposition. Therefore, it is followed by a noun, pronoun, or noun modifier. "As", on the other hand can be a conjunction as well as a preposition. Therefore, it can be followed by many types of words.
Your uses of "as" are correct. Some would call your sentence an error -- a comma splice -- because you have you two clauses joined by only a comma. However, because your two clauses are short and closely associated, many today would not object. In your sentence, I prefer "as" over "like".
You're welcome, but a separate post to say thank you is not needed. In the future, just click the "like" button below the post you appreciate. This saves others from believing that new question has been asked.
