How do you show a function is continuous

WebIt looks like this: It is defined at x=1, because h (1)=2 (no "hole") But at x=1 you can't say what the limit is, because there are two competing answers: "2" from the left, and. "1" from the … WebJul 9, 2024 · The following function factors as shown: Because the x + 1 cancels, you have a removable discontinuity at x = –1 (you'd see a hole in the graph there, not an asymptote). But the x – 6 didn't cancel in the denominator, so you have a nonremovable discontinuity at x = 6. This discontinuity creates a vertical asymptote in the graph at x = 6.
