WebSolution. Step 1: Check whether the function is defined or not at x = 0. Hence, the function is not defined at x = 0. Step 2: Calculate the limit of the given function. As the function gives 0/0 form, apply L’hopital’s rule of limit to evaluate the result. Step 3: Check the third condition of continuity. f (0) = lim x→0 f (x) WebJul 12, 2024 · The mathematical way to say this is that. must exist. The function's value at c and the limit as x approaches c must be the same. f(4) exists. You can substitute 4 into this function to get an answer: 8. If you look at the function algebraically, it factors to this: which is 8. Both sides of the equation are 8, so f (x) is continuous at x = 4 ...

WebDec 28, 2024 · Figure 12.7 shows several sets in the \(x\)-\(y\) plane. In each set, point \(P_1\) lies on the boundary of the set as all open disks centered there contain both … WebThis function is right continuous at point x = 4. The limit at x = 4 is equal to the function value at that point (y = 6). This is equal to the limit of the function as it approaches x = 4. Note that the point in the above image is filled in. On a graph, this tells you that the point is included in the domain of the function. bizhub c654e waste toner box
