Question

1. which graph shows x < 4?

a. open circle at 4, shading left
b. closed circle at 4, shading left
c. open circle at 4, shading right
d. closed circle at 4, shading right

Explanation:

• For inequalities like \(x < a\) (where \(a = 4\) here), we use an open circle at \(a\) because \(x\) is not equal to \(a\).
• Since \(x\) is less than \(4\), the values of \(x\) are to the left of \(4\) on the number - line.

Answer:

A. Open circle at 4, shading left
