WebJul 18, 2015 · Explanation: A function cannot be continuous at a point outside its domain, so, for example: f (x) = x2 x2 − 3x cannot be continuous at 0, nor at 3. It is worth learning that rational functions are continuous on their domains. WebJul 9, 2024 · Pre-Calculus For Dummies. If the function factors and the bottom term cancels, the discontinuity at the x-value for which the denominator was zero is removable, so the graph has a hole in it. After canceling, it leaves you with x – 7. Therefore x + 3 = 0 (or x = –3) is a removable discontinuity — the graph has a hole, like you see in ... dundee city council waste disposal https://oishiiyatai.com
