The verb "is" is present tense. The word "opened" is past tense. They don't agree. It either WAS opened from 9 to 5 at some time in the past, or it IS open from 9 to 5 on an on-going basis. Numbers one and two are both acceptable (Kathryn is right, #1 is better). Three and four are not.

Out of the four sentences you provided, only sentence 1 and sentence 2 are grammatically correct.
1. "The library is open from 9 to 5."
2. "The library is open 9 to 5."
Explanation:
Sentence 1: "The library is open from 9 to 5."
In this sentence, we use the present simple tense to indicate the regular and ongoing hours of operation for the library. The phrase "from 9 to 5" specifies the time range during which the library is open. This sentence is grammatically correct.
Sentence 2: "The library is open 9 to 5."
This sentence follows the same structure as sentence 1 but omits the word "from." However, it is still grammatically correct and conveys the same meaning: the library's hours of operation are from 9 to 5.
Sentence 3: "The library is opened from 9 to 5."
This sentence is not grammatically correct. The verb "opened" should be in the present tense to match the subject ("library") and indicate a continuous state of being.
Sentence 4: "The library is opened 9 to 5."
Similar to sentence 3, this sentence is also incorrect. The verb "opened" should be in the present tense ("open") to match the subject ("library") and convey a continuous state of being.
To summarize, only sentences 1 and 2 are grammatically correct, while sentences 3 and 4 contain errors.
