Question

graph the set of real numbers on a number line. {x|x>1} choose the correct graph below. a. number - line graph with open - circle at 1 and arrow to the right b. number - line graph with closed - circle at 1 and arrow to the right c. number - line graph with open - circle at 1 and arrow to the left d. number - line graph with closed - circle at 1 and arrow to the left e. none of the above

Explanation:

Step1: Understand inequality

The set $\{x|x > 1\}$ represents all real - numbers greater than 1.

Step2: Identify number - line representation

On a number line, for $x>1$, we use an open circle at 1 (because 1 is not included in the set) and an arrow pointing to the right (towards larger numbers).

Answer:

A.
