Question

pon Let Je)1 Find the open intervals on which f is concave up (down). Then determine the z-coordinates of all inflection points off 6x +8 1. f is concave up on the intervals 2. f is concave down on the intervals 3. The inflection points occur at z 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 z values or the word "none"

Explanation / Answer

1. None

2.(-infinity, infinity)

3.None

If we plot the graph of the function we have the maximum value at X=0 and minimum values as 0 at -infinity and infinity so there is only one Maxima so there is no point of infletion

The maximum value is 1/8 and minimum 0 at both infinity so it is concave down from -infinity to infinity and not concave up in any reason.
