I cant find number 2...
At least one of the answers above is NOT correct. (x) = x4-2x3 + 7x + 4. Find the open intervals on whichf is concave up (down). Then determine the x-coordinates of all inflection points (1 point) Let off. 1. f is concave up on the intervals (1,0) 2. f is concave down on the intervals INF-1)U(0,inf) 3. The inflection points occur at x1,0 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 x values or the word "none".
