WebJul 5, 2024 · You need to show that for every r > 0 there exists a d > 0 such that x-y < d => f (x) - f (y) < r. Example, let f (x) = x. Then for any r > 0 pick r = d then x - y < d = r => f (x) - f (y) = x - y < r. Example, let f (x) = x^2. Then for any r > 0 observe that x^2-y^2 = … WebTo find the domain of a function, consider any restrictions on the input values that would make the function undefined, including dividing by zero, taking the square root of a negative number, or taking the logarithm of a negative number. Remove these values from the set of all possible input values to find the domain of the function.
