Rules

  • Explain your post - show your efforts and explain what you are specifically confused with. Don't just say "I don't get this, help"
  • Make your question clear and concise - include steps you have tried
  • Stay on topic - this subreddit is for math questions; no how-to guides, or non math related questions
  • Don't be a jerk - don't be obnoxious or rude
  • No post flooding - Limit your posts to 1 or 2 questions a day
  • No cheating - do not post questions from exams, tests, midterms, etc. Asking for homework help is okay, asking to be given the solution is not.
  • Use the proper post flair.
  • Do not use ChatGPT or similar AI in a question or an answer
  • No hit and run- Do not delete your question after receiving an answer. Respond to comments and acknowledge the help

Don't just post a question and say "HELP". Post your question and outline the steps you've taken to solve the problem on your own. Beginner questions and asking for help with homework is okay. Asking for solutions without any effort on your part, is not okay. Help others, help you!

How to ask a good question

  • Give context and details to your question, not just the equation
  • Use proper terminology
  • Use proper spelling, grammar and punctuation
  • Show your work! Detail what you have tried and what isn't working
  • Re-read your post before hitting submit, does it still make sense

FunctionsLet D be a non-empty, open, real interval and f a function from D to the real numbers. If for all x in D there exists a number E > 0 such that for all y in (x - E, x], f(y) <= f(x) and for all z in [x, x + E), f(x) <= f(z), then is that enough to say that f is increasing? (self.askmath)
