Question

Which interval notation accurately represents the domain?

(–∞, 7) U (7, ∞)
(–∞, 5) U (5, ∞)
(–∞, 0) U (0, ∞)
(–∞, 10) U (10, ∞)

Answer 1

I don’t have the function or graph, so I can’t determine which interval is correct. Please tell me the function or show the graph.

Quick guide meanwhile:
- (–∞, 7) U (7, ∞) = all real numbers except x = 7 (e.g. 1/(x−7))
- (–∞, 5) U (5, ∞) = all real numbers except x = 5 (e.g. 1/(x−5))
- (–∞, 0) U (0, ∞) = all real numbers except x = 0 (e.g. 1/x)
- (–∞, 10) U (10, ∞) = all real numbers except x = 10 (e.g. 1/(x−10))

If you paste the expression or image, I’ll pick the correct interval and show the steps.
