WebNow to find which interval is concave down choose any value in each of the regions, and . and plug in those values into to see which will give a negative answer, meaning concave down, or a positive answer, meaning concave up. A test value of gives us a of . This value falls in the range, meaning that interval is concave down. WebOn a given interval that is concave, then there is only one maximum/minimum. It is this way because of the structure of the conditions for a critical points. A the first derivative must …
