Question

which graph represents $x \
eq 4$?
a. open circle at 4 with shading on both sides
b. closed circle at 4 with shading on both sides
c. closed circle at 4 with no shading
d. no circle at 4, but shading everywhere else

Explanation:

The inequality \(x
eq 4\) means all real numbers except 4. On a number line, an open circle at 4 indicates 4 is excluded, and shading both sides covers all other numbers. Closed circles include the point, so b and c are wrong. Option d incorrectly describes the circle notation. Thus, a is correct.

Answer:

a. Open circle at 4 with shading on both sides
