Abstract

It's that time of year again: I have to set some calculus questions for school exams. Naturally I want to include a question about a cubic in which pupils would be expected to find the -intercepts as well as the turning points. It's easy if we allow one of the factors of the cubic to be repeated, so that the graph has one of its turning points on the -axis, since that way we ensure that the turning points have rational coordinates and that the pupils have a moderately easy task.
