(1 pt) Let f(x) on which f is concave up (down). Then determine the r-coordinates of all inflection points of j Find the open intervals T5 IS concave up on the intervals is concave down on the intervals The inflection points occur at 1. 2. 3. Notes: In the first two, your answer should either be a single interval, such as (0,1), a comma separated list of intervals, such as (-inf, 2), (3,4), or the word "none". In the last one, your answer should be a comma separated list of T values or the word "none"
