Question

The graph of an inequality has an open circle at 8, and the ray moves to the right. What inequality is graphed?

x>8
x>8
x<8

Answer 1

Answer:  Hello there!

The open circle means that the set does not contain that extreme, so with this information, you could discard the third and fourth options.

The ray moves right, in the usual notation, the real numbers increase to the right, then, in this case, we are looking at the set of numbers bigger than 8, that does not contain the number 8.

then the inequality graphed is x > 8, and this means that the right answer is the first option.
