Chapter 5.1, Problem 52E

point Let f(x) = -x* - 9x' + 5x + 4. Find the open intervals on which f is concave up (down). Then determine the x-coordinates of all inflection points of f. %3D 1. f is concave up on the intervals 2. f is concave down on the intervals 3. The inflection points occur at x = 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".

Can someone answer these questions pls thanks

Evaluate f(3) and f(3.1) and use the results to approximate f '(3). (Round your answer to one decimal place.) f(x) = x(3 – x) f (3) 0 Need Help? Read It Watch It Talk to a Tutor
