what is the difference in use between 'incredible' and 'incredibly'?

[teachingamanda]

My student recently asked me to explain why 'incredibly' is used in this sentence and I am stumped. If anyone can offer insight I would appreciate it:

I'm asking the INCREDIBLY low price of $65.

The form of 'incredibly' here is an adverb, right? Yet, it is placed as an adjective. The answer may be really obvious so I apologize if this is a stupid question!

Many thanks!

'Incredibly' is indeed an adverb. One of an adverb's functions is to modify an adjective, and 'incredibly' modifies the adjective 'low' here. How low is the price?-- Incredibly low!

The feat was incredibly incredible.

(adverb form modifying adjective form)
