Answer:
Domain: {x | x < 3} or all real numbers less than three
Step-by-step explanation:
The domain is the x-value of the linear equation. Since the graph is shown as a ray starting at 3 and going on and on below 3 (into negative numbers), any number above three cannot be part of the domain. The domain is written as {x | a < x < b}, where a and b are real numbers. In this scenario, the first number, a, is irrelevant, because there is no limit for how much below x the number will go, as it is a line segment.
Hope this helps!
