Reply. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. Other than just pointing these things out on the graph, we have a very specific way to write them out. Officially, for this graph, we'd say: f has a relative max of 2 at x = -3. f has a relative max of 1 at x = 2. An extremum is a maximum or minimum. Get the free "Extrema Calculator w/ Domain" widget for your website, blog, Wordpress, Blogger, or iGoogle. You find local maxes at x = –2 and x = 2 with the second derivative test; you find a local min at x = 0 with street smarts.. Start by finding the critical numbers. Derivative Calculator Find Local Extrema (explained) Derivative Calculator. Now determine the y coordinates for the extrema.. So, x = 0, 2, –2. Reply. Now get the second derivative.
