Hi Sir! You said that at a point of inflection f''(x) = 0, however, I have found examples of graphs which this is not true for... Is it the case that it will always be true in my exam duye to the nature of the questions set?

[TimOyewole]

one question - how does our answer at the end show that there is only one point of inflection?
