Answer:
Explanation:
The answer is D. The graph to the left of x = 1 has an open hole at the x value of 1, and the graph does not continue on past the x value of 1. Therefore, the domain of that function is all values of x that are to the left of x = 1. The hole is open because the inequality statement doesn't have a line under the inequality symbol that says we have to include it. It is, however, included at the x value of 1 on the line.
