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.

The domain of a graph is the set of input values the graph can take.

The graph that represents y = [x] over the domain 2≤x≤5 is the 4th graph.

The domain is given as:

[tex]\mathbf{2 \le x \le 5}[/tex]

The inequalities at 2 and 5 are both "less than or equal to"

In inequalities, "less than or equal to" is represented by a closed circle

This means that, the circles at x = 2 and x =5 on the graph must be a closed circle.

From the given options, we have the following observations

  • The domain of graph 1 stops at x = 3 with a close circle
  • Graph 2 (beside graph 1) has open circles at x =2 and x = 5
  • The domain of graph 3 (under graph 1) stops at x = 4, with an open circle
  • Graph 4 has closed circles at x =2 and x = 5

Hence, the graph that represents y = [x] over the domain 2≤x≤5 is the 4th graph.
