Is f increasing at x=3?

Sign up or log in to save this to your schedule and see who's attending!

Many folks assert that functions cannot increase "at a point". However, we calculus teachers continue to ask a variation of the question, "Is f increasing at 3?" without talking about what we mean. How can we assert that a function cannot increase at a point and then ask our students that very question. For some examples of calculus teachers asking such questions, see the 2013 Free Response questions which can be found at AP Central. This year questions AB/BC 12 and AB 2d asked if a function was increasing or decreasing at a point. I will posit a definition of "increasing at a point"and explore its ramifications.
