A: This question is puzzling. I don't know whether I asked a math question or a geometry question. Is it a function image or a figure in geometry? It is doubtful whether this ambiguity of asking questions can be explained clearly if it is taught to children.

If it is a function image problem, it is an analytic geometry problem. If the problem of simple geometry belongs to the geometric category. Although mathematics includes geometry; But the solutions are different. Graphics in geometry are mainly plane graphics and three-dimensional graphics. If it is a function image problem, it is usually a plane image problem. You can tell the child what the main problem is, and I can help him answer it. There are many experienced teachers on the Internet who can answer them. It will definitely be much better than your answer; Judging from your language ability, you don't need to teach your children to learn; I'm afraid you'll delay the children, even though your math scores are outstanding.
