On a number line there is an open point at 3 and shading to the left. What is the inequality?

Answer and explanation

Correct answer: x < 3

The governing concept is interpreting inequality notation from a number-line graph. An open point at 3 means that 3 itself is not included in the solution set; this corresponds to a strict inequality, either < or >. Shading to the left represents numbers smaller than 3, so the correct relation is x < 3. Therefore option A is correct. Option B has the correct leftward direction but incorrectly includes 3, which would require a closed point. Options C and D represent values to the right of 3, so they contradict the shading direction; D would also include the endpoint. In interval notation, the graph represents (−∞, 3). A test value such as x = 2 lies in the shaded region and satisfies 2 < 3, while x = 3 is excluded exactly as the open circle indicates.
