WebAnswer: The given function has no VA but it has a hole at x = 2. Example 3: The vertical asymptote of a function f (x) = log (2x - k) is x = 3. Then what is k? Solution: The VA of the given function is obtained by setting 2x - k = 0. Solving this, we get 2x = k (or) x = k/2. But it is given that VA is x = 3. So k/2 = 3. From this, k = 6.
