Question

graph the set of real numbers on a number line. {x|x≥ - 4} choose the correct graph below. a. number - line with closed - circle at - 4 and arrow to the right b. number - line with closed - circle at - 4 and arrow to the left c. number - line with open - circle at - 4 and arrow to the left d. number - line with open - circle at - 4 and arrow to the right e. none of the above

Explanation:

Step1: Understand inequality symbol

The symbol $\geq$ means "greater than or equal to". So $x\geq - 4$ includes $-4$ and all real - numbers greater than $-4$.

Step2: Analyze number - line graph representation

On a number line, a closed - circle is used to represent that the number is included in the set (because of $\geq$), and an arrow pointing to the right represents all numbers greater than that number.

Answer:

A.
