Question

Which graph represents y=⌈x⌉ over the domain 2≤x≤5?

Answer 1

Answer:

Fourth graph.

Step-by-step explanation:

The black circles represent closed intervals, and the white circles represent open intervals.

So, according to function domain given, x = 2 is part of the domain, so must have a black circle. X = 5 is also closed interval, that is part of the domain, so also must have a black circle.

The only graph that has this characteristics is the fourth.

Answer 2

The fourth graph is the correct answer
