The graph below represents which of the following inequalities?

VIEW ANSWER
Answer: \[x\ge-1\]

Explanation

Since the circle at −1 is closed, that means that −1 should be included.

Eliminate answer choices A, B, and E, which do not include –1.

Since the graph goes to the right, the inequality must be greater than or equal to −1.
