Monotonicity doubt using LVMT
So I shared the photo of question and the solution.
In the solution it directly says a functions is continuous or nor or whether a functionsi differentiable. Is there any quick method to find whethere a function is continuous or not ? Or it is just solution doesn't show the whole process of finding it ?
