Answer:
B. 3≤x≤ 6
Step-by-step explanation:
When a question asks for the domain of a function, it is asking for <u>all possible x-values</u>. Look at the graph of the function- there are no points on the graph where x=1, so we know that C and D are definitely wrong since they include 1. The two that are left look very similar, but A means "3 is greater than or equal to x, x is greater than or equal to 6." This has to be wrong because it says that 3 is greater than 6, which is obviously incorrect. The only answer left is B, which is correct because it includes all possible x-values.
lmk if this is incorrect or hard to understand, hope this helps!!!
