Positive derivative on the interval(s) Negative derivative on the interval(s) Title: Re: The function graphed above has: Post by: bio_man on Jul 18, 2019 There will be positive derivative on:
[-∞, -2.5) (0, ∞] Negative derivatives on: (-2.5, 0) I hope this helps. Oh, and by the way, at the vertices, the tangent is horizontal, so the derivatives are ZERO. This is why I used ( and ) instead of [ and ] in those situations. |
