Like any other i-adjective, they can be conjugated but I read a few example
sentences of the i-adjective "無い" and I can't find any sentences where it was
conjugated.

question
conjugations
Can 無い be conjugated?
Yes ない conjugates like any other i-adjectives do.

  * 大きくなかった。 It was not big.
  * リンゴはなかった。 There were no apples.
  * 高くなくて、安くもない。 It is neither expensive nor cheap.

The ku-form (aka adverb form) is sometimes used, too, but it usually sounds
slightly awkward:

  * [?] 美しくなく踊った。 He danced not beautifully.
