Answer:
B
Explanation:
the domain is the values of x covered by the graph.
the left side has a solid circle at x = - 1 meaning that x can equal - 1
the right side has a solid circle at x = 3 meaning x can equal 3 , then
domain : - 1 ≤ x ≤ 3
domain is all values of x that work. The function stretches from -1 to 3 and the dot is filled in so x values are greater than or equal to -1 and less than or equal to 3
